摘要： A fluid drive assembly has a pump, a variable displacement motor, a fluid circuit connecting the pump to the motor, and an actuator device for controlling the displacement of the motor. The actuator device is movable between a first position at which the displacement of the motor is at a preselected maximum and a second position at which the displacement of the motor is at a preselected minimum. A control system for the fluid drive assembly includes a source of fluid at a first preselected pressure value. A valve device is connected to the source of fluid and to the actuator device for controlling the fluid flow therebetween and is movable between a first position at which the source of fluid is in communication with the actuator device and a second position at which the source of fluid is blocked from communication with the actuator device. A first device automatically moves the valve device to the second position in response to the fluid pressure in the fluid circuit exceeding a second preselected pressure level. A second device retains the valve device in the first position until the fluid pressure in the fluid circuit decreases from the second preselected pressure level to a third preselected pressure level.

摘要： Fluid control circuits employed on construction vehicles to control the actuation of various work cylinders oftentimes include a system for sensing the fluid pressure in the cylinder and communicating such fluid pressure to a control device in signal form to closely control the displacement of a pump, the flow capacity of a pressure compensated flow control valve, or the like. The sensing system is normally associated with the spool of a directional control valve which must travel a substantial distance to effect extension or retraction of the cylinder and normally requires an "anti-rotation" device to insure proper alignment of the various ports and passages. Conventional high pressure systems of this type also pose potential leakage problems.This invention overcomes such problems by providing an improved load sensing system (45) including an annular land (32) defined on a spool (26) of a control valve (23) and an annulus (46) disposed axially between first (36) and second (37) outlets of the control valve (23) and further disposed to circumvent the land (32) of the spool (26).

摘要： An output shaft is rotatably mounted on a stationary support to selectively actuate a control valve of a hydrostatic transmission. A pair of levers are pivotally mounted on the output shaft in scissored relationship thereon and an actuating arm is rotatably mounted on the support to engage camming surfaces defined on first ends of the levers. A drive pin is secured to the output shaft to have opposite ends thereof engage bearing surfaces defined on second ends of the levers whereby swinging movements of the actuating arm in opposite directions will alternately transmit pivotal movements of the levers to the output shaft to control actuation of the control valve. The second ends of the levers are biased away from each other by a coil spring to normally engage the bearing surfaces with the drive pin.

The improvement serves to control the pump output. In a broad sense, the improvement comprises means internal of said pump body and acting between said pump body and said swash plate for biasing the swash plate towards a zero displacement position corresponding to a minimum displacement of the pump, and means responsive to discharge pressure of the pump reaching a first magnitude for overriding the biasing means and rotating the swash plate towards a full displacement position corresponding to a maximum displacement of the pump said overriding means comprising servo valve means within said pump body and pilot pump means acting to initially shift said servo valve means to allow discharge pressure to be applied in opposition to said biasing means.

摘要： A control for selectively controlling operation of left and right side drives for providing a selective steering drive of a vehicle. The control includes a single manually operable control lever and mounting structure for transmitting selective movement of the control lever through suitable push-pull linkages to the vehicle drives. The control is arranged to effect a change in the gain of output lever portions thereof in effecting the desired controlled steering operation of the drives. The change in gain is controlled by the engagement of rollers associated with the control lever against output levers associated one each with the push-pull linkages and left and right side vehicle drives.

摘要： A hydrostatic unit of the type contemplated by the present invention includes one or more pump and motor combinations interconnected by means of a conventional closed loop. Controls for the hydrostatic unit include a speed control and vent valve assembly as well as a venturi manifold which functions to normally establish a selected pressure differential in a pair of supply conduits for determining instant operating conditions for the transmission. In order to automatically regulate displacement of each pump unit in response to prime mover speed, an underspeed actuator valve unit includes a piston which is hydraulically responsive to the differential pressure in order to adjust operation of a lever which controls displacement of the pump unit. A part throttle control valve prevents the underspeed actuator from reducing displacement of the pump unit when speed of the prime mover is reduced by a manual throttle control.

摘要： PCT No. PCT/US 79/ 00573 Sec. 371 Date Aug. 6, 1979 Sec. 102(e) Date Aug. 6, 1979 PCT Filed Aug. 6, 1979Conventional directional control valves and the like normally include relatively complex and spatially separated centering and detent mechanisms for selectively maintaining a valve spool at centered and detent-held positions, respectively. Such valves are normally bulky and the casings therefor, primarily since they require machining, cannot be manufactured by die-casting methods. This invention overcomes the above problems by providing for the precise positioning of a valve spool (11) in its centered position by interassociating and engaging a centering mechanism (17) with a detent mechanism (30) by a stop (27), defined on a retainer (24) of the detent mechanism (30).

摘要： A fluid drive vehicle has an engine speed control, a fluid drive transmission having a fluid actuator device for moving a control element from its neutral position progressively to increase the drive ratio, and a control system which includes a first fluid circuit which has a control valve movable from a neutral fluid blocking position progressively to increase the flow of pressurized fluid from an auxiliary pump to the fluid actuator device. A fluid responsive servo mechanism moves the control valve from the neutral position while a fluid motor is operative to move the engine speed control from an idling position to increase the engine speed. A second fluid circuit includes a pressure control valve manually actuatable from a neutral fluid flow blocking position to an actuated position for providing fluid flow therethrough from the auxiliary pump to the servo mechanism and the fluid motor and for regulating and maintaining the pressure of the fluid delivered to the servo mechanism and the fluid motor at a pressure level commensurate with the actuated position, and an inching valve selectively manually actuatable from an open position which permits substantially unrestricted fluid flow to the servo mechanism to an actuated position restricting fluid flow to the servo mechanism for reducing the pressure of the fluid delivered to the servo mechanism while maintaining the pressure of the fluid directed to the fluid motor at the pressure level determined by the pressure control valve.
