| PURPOSE: To easily obtain fluid which drives actuators by closing the exhaust valve of the one actuator at higher pressure in response to a difference between pneumatic pressures in the actuators, and opening the exhaust valve of the other actuator. CONSTITUTION: When a spherical part 24 is manually constricted, increased pressure closes flap valves 30, 31 and opens a flap valve 34 to allow air into an actuator chamber 14. Then the increase in pressure causes closing of an exhaust valve 62, and a rod 60 opens an exhaust valve 64 in the other actuator chamber 16 to communicate with the atmosphere via an outlet 58. When the spherical part 24 is loosened, the flap valve 34 closes and the flap valves 30, 31 open to draw a large amount or air into the spherical part 24. Then the expansion of a film 18 caused by an increase in pneumatic pressure within the chamber 14 causes the movement of a projecting part 22 to tilt mirror support 10. When the spherical part 44 is constricted, air enters the other actuator chamber 16, tilting the mirror support 10 in the opposite direction. COPYRIGHT: (C)1990,JPO | ||||||

| PURPOSE: To ensure good frequency dynamic characteristic by connecting numbers of piezoelectric pump elements as a pumping device to both fluid chambers of a cylinder through two check valves respectively functioning oppositely. CONSTITUTION: Conveyance chambers 14 to 17 of pump elements 10 to 13 are connected to fluid chambers 4, 4' bordered by the piston 2 of a cylinder casing through two check valves 10a, 10b; 11a, 11b; 12a, 12b; 13a, 13b functioning in the opposite directions. For example, the pump element 10 is controlled to make delivery strokes by the piston 2 aparting from the terminal position and starting from the state of being in a midway position and the pump element 11 to make an intake stroke, while conveyance chambers 16, 17 become ignorably minimum volume with pump elements 12, 13 extended to their maximum. Thus the motor invented by this invention includes excellent oscillation characteristic even under high oscillation frequency. COPYRIGHT: (C)1990,JPO | ||||||

The hydraulic system includes two component hydraulic systems, the first of which is provided with a mechanical linkage structure associated with spring-suspended parts at the front and rear of the automobile, two measuring cylinders having pistons displaceable therein and connected to the linkage structure, and a conduit which connects the two measuring cylinders with one another and with the work space of a common working cylinder of the hydraulic system. The second component system is provided with a second working cylinder having a piston displaceable therein and a work space which is connected by a conduit to the common working cylinder, as well as a pair of headlight position adjusting linkages connected to the pistons of the two working cylinders on the one hand and adapted for mechanical connection to pivotably mounted headlights of the automobile, on the other hand. This hydraulic system is improved by providing it with a fill-up valve in one, and a vent valve in the other of the component systems, and with a hydraulic conduit interconnecting the two systems in which conduit there is interposed a shut-off structure which can be opened in the direction of liquid flow from the fill-up valve to the vent valve, while the entire hydraulic system is being filled. | ||||||

| Manoeuvring arrangement, comprising a manoeuvring lever (1) and a manoeuvring console and provided with at least one pivot hinge by means of which the lever is articulated relative to the manoeuvring console for switching between a number of manoeuvring positions. The manoeuvring positions of the manoeuvring lever about the pivot hinge are intended to be converted to corresponding operational states of an arrangement which is to be manoeuvred. The pivot hinge (6) permits pivoting of the manoeuvring lever relative to the manoeuvring console about an unlimited number of spatial pivot axes. The arrangement includes a number of controllable devices (13-16) which are mechanically coupled to the manoeuvring lever and which limit the pivoting movement of the manoeuvring lever. A number of sensor members (31, 32, 33, 34, 48, 49) detect a manoeuvring force initiated on the lever and a manoeuvring position of the lever and control the devices so as to permit a selected movement as a function of control conditions established by means of a control unit (28). | ||||||

| A device for adjusting the relative angular position of two mutually articulated structures comprising a first and a second element (5, 6) respectively connected to said structures, that rotate mutually around the axis of articulation of said structures and that define two chambers between them whose volume varies inversely as a result of the relative rotation of said elements. Said variable-volume chambers are connected together by conduits (3). The chambers and the conduits are filled with a fluid that flows from one chamber to the other through the conduits as a result of the relative rotation of the two elements around their axis of articulation. Valves are provided for interrupting communication through said conduits (3), so as to prevent the passage of fluid from one chamber to the other and consequently lock the two elements in any relative position to which they have been adjusted. | ||||||

| A reversibly actuatable fluid hydraulic pump is described for use in a hydraulically driven elevator. The pump comprises a cylinder and a piston linearly actuatable within the cylinder by means of a ball screw race disposed over a spindle and connected to the piston. The shaft of the piston is hollow to receive the spindle as the piston is drawn along by virtue of the motion of the race along said spindle, and seals are provided at the free end of the piston which sealingly engage against the walls of the cylinder, and on the cylinder which sealingly engage with the shaft of the piston. A further feature of the invention is the provision of a compressible gas between the end of the cylinder and the end of the piston so that the expansion thereof reduces the work required to move the piston out of the cylinder, whereas when the system is relaxing, the compressible gas provides extra resistance and thus a smoother motion. | ||||||
