| An arrangement for selectively making available hydraulic power in separate hydraulic circuits comprises two displacement machines, two free-wheels and a drive unit that is preferably arranged between the displacement machines. The free-wheels block in opposite directions and are coupled to the displacement machines. Consequently, the first displacement machine is driven in a first rotating direction of the drive unit while the second displacement machine is only driven in a second, opposite rotating direction of the drive unit. This makes it possible to realize an intermittent operation for selectively making available additional hydraulic power in separate hydraulic subsystems by choosing the rotating direction accordingly. This arrangement can reduce the weight and the complexity of a hydraulic system. | ||||||

| Hydraulic control apparatus for automatic remote control of a hydraulic actuating ram. The apparatus has a double-acting slave cylinder connectable hydraulically to an actuating ram, and a double-acting master cylinder the piston of which is mechanically connected to the piston of the slave cylinder, the master cylinder being operable by hydraulic pressure supplied via a pilot-operated valve arranged automatically to reverse the stroke of the master ram at limits set according to the desired stroke of the actuating ram. The control apparatus may be used for controlling actuating rams which effect reciprocating pivotal movement about one or more axes of a water jet monitor.

| 55 | Hydraulic power brake booster | US3691903D | 1971-09-13 | US3691903A | 1972-09-19 | SHELLHAUSE RONALD L |
| A hydraulic power brake booster powered by power steering gear pump pressure and utilizing an open-center valve so that fluid flows through the booster without pressure reduction when the booster is not activated. The valve assembly includes a radially floating valve seat which provides for self-centering, permits a valve separation operation to pass viscous cold hydraulic fluid or any elements which may tend to overly restrict the valve. It also includes a valve face design providing entrance and exit angles defining a venturi-type passage conductive to laminar flow with consequent reduction in valve noise, and has a hydraulic reaction mechanism which includes an arrangement for supported line pressure.

| Arrangement for amplifying power applied to a load member including a power system having spring means for moving a pivoted beam in one direction and a fluid system for moving the beam in the opposite direction. A lever, pivotally carried by the beam, is connected at one end to the load member. Manual control means are arranged to move the other end of the lever, which movement is effective to vary the pressure in the fluid system and thereby control movement of the pivoted lever.
