| 171 | Distributor of a fluid under pressure | US720289 | 1991-06-25 | US5193345A | 1993-03-16 | Leonardo Cadeddu |
| The distributor is used for supplying a fluid coming from a source of fluid under pressure and under a pressure which is a function of the pressure of a control fluid. The distributor comprises, in a bore (3) made in a body (1), a double valve consisting, on the one hand, of a first piston (21), one end of which defines with a first plug (5) a control chamber (23) receiving the control fluid, while the other end (27) is pierced with a conduit (29) connected to a reservoir of fluid under low pressure (11), an annular chamber (31) surrounding the first piston (21) and being connected to the consumer circuit of the distributed fluid, and, on the other hand, of a disk (33) forming a shutter and resting on a circular seat (35) stationary relative to the body (1) by way of a return spring (43). The disk (33) is opposite the other end (27) of the first piston, this being capable, under the action of the pressure prevailing in the control chamber (23), of coming up against the disk (33), so as to close communication between the conduit (29) and the annular chamber (31), and then of displacing the disk (33) so as to open communication between a conduit for the inlet of the fluid under pressure and the annular chamber (31). The distributor comprises, furthermore, a second piston (39), one face of which is fixed to the face of the disk (33) opposite the seat (35) of the latter and the other face of which defines with a second plug (7) closing the bore (3) a balancing chamber (41) communicating permanently with the annular chamber (31). | ||||||

| A diaphragm module for pneumatic control systems comprises at least a pressure comparing stage and a force/pressure transducer controlled by said stage. The design of said module comprises chambers in a housing divided by diaphragms, wherein the force transmission between the diaphragms is achieved by intermediately arranged diaphragm disks. For a low friction mounting of the diaphragm disks in the housing without fixation with the intermediately arranged diaphragms the module comprises the following design: The diaphragm disks (36-39) comprise central pin projections (40) and recesses (44), wherein the pin projection of a diaphragm disk each is inserted into a recess of an adjacent diaphragm disk via a central hole (35) provided in the comparing or tightening diaphragm (31, 33, 34), respectively; the housing (11-16) and the diaphragm disk (36-39) comprise annular ribs (42) which are pressed into the diaphragms (30-34) for tightening when pressure is applied; and at least two diaphragm disks (36-39) comprise in their plane surfaces concentric annular grooves (43) which are engaged by annular collars (41) of related diaphragms (FIG. 1). | ||||||
| 175 | Hydraulic pressure integrator | US73707 | 1979-09-10 | US4300352A | 1981-11-17 | Henry L. Williams |
| A hydraulic pressure integrator for averaging a plurality of independent input pressures comprising a base plate, a pivot plate mounted above the base plate for pivotal movement about a horizontal pivot axis disposed above and parallel to the base plate, a plurality of input cylinders mounted between the base plate and the pivot plate, each input cylinder having a slidable input piston mounted therein and adapted to contact the pivot plate along a given side of the pivot axis, and a single output cylinder mounted between the base plate and the pivot plate and having an output piston slidably mounted therein and adapted to contact the base plate on a side of the pivot axis opposite from the input pistons, each input cylinder receiving one of the independent input pressures. When the input pressures raise the input pistons contacting the pivot plate, the resulting force creates a torque along the pivot axis, thereby depressing the output piston and producing an output pressure from the output cylinder which is an average of the input pressures. | ||||||
| 176 | Device for monitoring fluid pressure in mechanisms such as hydrostatic fluid bearings | US509650 | 1974-09-26 | US3931738A | 1976-01-13 | Elpidifor Paramonoff; Frederick C. Olsen |
| Pressurized operating fluid, such as oil for hydrostatic fluid bearings, is directed into a chamber against a plunger urging the plunger into a first position. A monitoring pressure force slightly less than the force of the operating fluid when the operating fluid is at a minimum working pressure is exerted against the plunger tending to move the plunger from this first to a second position. Thus, when the pressure of the operating fluid drops below the minimum working pressure, the plunger is moved to its second position and such movement is sensed, thereby sensing the malfunction. | ||||||
| 177 | Condition responsive control device with capacity for independent adjustment of control points and transducer therefor | US42243273 | 1973-12-06 | US3911238A | 1975-10-07 | OTTO NOEL A; RIEFLER ROGER G |
| A control device having a pressure sensing element coupled to a balance plate. The balance plate, in turn, is coupled to a microswitch by an actuating rod. Variations in pressure displace the sensing element which, in turn, pivotally displaces the balance plate sequentially about first and second axes. A pair of springs are coupled to the balance plate by bosses which extend different distances from the balance plate. The bosses facilitate use of identical springs and adjusting members in a control device where the differential between control points is fully adjustable. The control device has a housing including upper and lower sections, the upper section having a microswitch associated therewith, the lower section having the balance plate and associated elements disposed therein. A recessed space at the exterior of the housing is defined by the upper and lower housing sections. The adjusting members for the springs extend into the recessed space so as to be readily accessible from the exterior of the housing. The control device includes a detachable pressure transducer which facilitates conversion of the control device from one application to another.

| 178 | Differential flow pressure switch for dual valve circuits | US38889473 | 1973-08-16 | US3865218A | 1975-02-11 | JONES JR CLARENCE O |
| It is known to use parallel dual valves for controlling operation of cyclic machines such as power presses and press brakes. Dual solenoid valves are used so that the machine will continue to cycle properly even though one valve fails to close. The present control apparatus provides means for shutting down the machine when one valve fails to close so that operation will not continue with reliance only on the one remaining functional valve. A pressure-responsive element is normally centered in a pressure passage by connecting the pressure output of the two valves to opposite ends of the pressure passage. If one valve fails to close, pressure therefrom shifts the pressure-responsive member from a normally centered position. A normally open reed switch which is interposed in the valve energizing circuit is held closed by a magnet included in the pressure-responsive member but when the latter is shifted due to valve failure the reed switch opens and machine operation is terminated until the abnormality is corrected and the valve energizing circuit is reset.

| Pneumatic instrumentation apparatus of the planar type comprising a laminar sandwich construction one layer of which is a stiffly-flexible metal plate formed with cut-out openings to define an interior flat operator pivotally and sealingly supported at intermediate pivot axis region. The operator includes two separate but integral sections, located on opposite sides of the pivot axis. One of these sections is sub-divided into a plurality of separate side-by-side segments each integral with the pivot axis region, and arranged to supply separate torques to such pivot axis, or to move therewith in response to forces applied by other segments of the operator. Such multisegmented pivotable operator is embodied in a variety of instruments, including process controllers, a ratio unit, and a digital-to-analog converter.
