| 181 | Hydraulic remote control device for controlled members, such as external rear view mirrors on vehicles | US207054 | 1988-05-24 | US4918920A | 1990-04-24 | Bernard Duroux |
| The device comprises a manipulator (148) whose body (149) houses deformable positioning transmitter bags (145 to 147) each connected by a corresponding hydraulic circuit to a positioning receiver comprising a deformable bag (130 to 132, 133 to 135), whose increases in volume in response to the compression exerted by the user on at least one of the positioning transmitter bags (145 to 147 control a change of the positioning of at least one controlled member. The device may contain a connector connecting the transmitter bags to the receiver bags, and also path switching hydraulic circuits permitting the selective control of one of two different members by a single manipulator. Application in particular to the control of external rear view mirrors on vehicles. | ||||||

| An improved rephasing master cylinder in which the cylinder wall approximate the end of the cylinder has a longitudinal bleed passage in the cylinder wall at one end connected to a lateral passage opening into the forward cylinder chamber while the opposite end of the longitudinal passage connects with the rearward chamber of the cylinder when the cylinder piston is located therebetween. This longitudinal bleed passage permits the restricted flow past the master cylinder piston when the piston is nearing and at the end of its stroke, thereby causing both master and slave pistons to complete their respective strokes. | ||||||

| A light guide with a liquid light transmissive medium is connected to a variable pressure source, such as a controllable pump, and a hydraulic pressure take-off is connected to the light guide, for example adjacent the light exit window, to control the position of a positionable element, typically an optical system, such as a fluid lens, a movable lens, a diaphragm or the like, with respect to the exit light window from the light guide tube as a function of the pressure applied to the light transmitting liquid within the tube. Thus, the light guide can function simultaneously as a light guide and as a hydraulic servo pressure control element, to control the light output or the position of another element linked to the hydraulic servo positioning piston-cylinder arrangement coupled to the light transmitting fluid in the light guide. | ||||||

| 6. A hydraulic actuator assembly comprising:An elongated cylinder;First and second longitudinally spaced fluid inlet and outlet fittings in the cylinder wall;First and second longitudinally spaced fluid inlet and outlet ports through the cylinder wall communicating respectively with the first and second inlet and outlet fittings;First and second longitudinally spaced fluid escape orifices through the cylinder wall communicating respectively with the first and second inlet and outlet fittings, one orifice adjacent each of said ports, the longitudinal spacing between the orifices being less than the longitudinal spacing between said ports, and the fittings, ports and orifices being in substantial longitudinal alignment along the cylinder wall;A piston having limited reciprocable movement in the cylinder; andAn annular seal or packing carried by the piston for sealing between the piston and the internal wall of the cylinder, and for thus dividing the cylinder into first and second fluid pressure chambers,The location of the piston at each end of its permitted stroke and the spacing between and location of the ports and the orifices being so related, each to the other, that:A. when the piston is at one end of its stroke the piston seal is located between the first port and the adjacent first orifice, the first cylinder chamber is in open communication with the first fitting through the first port, and the second cylinder chamber is in restricted communication with the first fitting through said first orifice; andB. when the piston is at the other end of its permitted stroke the piston seal is located between the second port and the adjacent second orifice, the second cylinder chamber is in open communication with the second fitting through the second port, and the first cylinder chamber is in restricted communication with the second fitting through the second orifice. | ||||||
| 187 | Hydraulic system for automatically adjusting the positions of headlights of an automobile | US33710873 | 1973-03-01 | US3828179A | 1974-08-06 | STRAUB S |
| What follows is the description of an improved hydraulic system for automatically adjusting the positions of headlights of an automobile. 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.
