摘要： The invention concerns the control of the suspended weight from a vessel subject to wave and tidal action and particularly a vessel employed in connection with submarine drilling operation. The particular improvement concerns the modulation of the liquid in a hydraulic-pneumatic suspension system subject to heave action so as to maintain the volume of the gas in the accumulator substantially constant during each portion of the cycle action of the heave. This may be accomplished by adding liquid to the accumulator during one portion of the heave cycle and withdrawing liquid from the accumulator during another portion of the heave cycle.

摘要： An implement hydraulic circuit including a pilot operated flow amplifier directional valve for controlling communication between a source of primary actuating fluid and a hydraulic motor. A pair of valve spools in the valve provide separate regulated flow paths for an inlet passage and an outlet passage respectively with a pair of work ports. An actuating chamber is associated with one end of each of the spools and may each be selectively communicated with a separate source of pilot fluid for actuation of either of the spools to communicate the primary source with either side of the motor. The other spool is positioned by fluid displaced from the motor to communicate the displaced fluid to the outlet passage for return to a reservoir. The configuration of the spools and their arrangement in the valve provide a capability of metering flow from motor to reservoir to prevent overrunning of the motor.

摘要： An open center directional control valve assembly having an unloading valve that diverts inlet flow to drain without passing through the entire assembly whenever all control valves are in neutral. When one or more of the control valves are operative, to actuate their associated motors at desired speeds, the unloading valve is automatically positioned by the pressure difference between inlet pressure and the highest motor pressure to deliver the necessary flow to operate the motors at the desired speeds while diverting the remainder of inlet flow to drain.

摘要： A hydraulic system including two or more hydraulic components separately operable by means of predetermined mutually arbitrary quantities of pressure medium supplied from a common source of the latter via a common feed conduit through respective individually regulatable quantity control valves. Each quantity control valve incorporates a throttle arrangement and a control slide which are adapted to supply a maximum quantity of pressure medium to their hydraulic component by balancing the pressure on the control slide in opposite axial directions. The control slide in a first axial direction is under a pressure load in front of the throttle arrangement and in an opposite axial direction under a pressure load behind the throttle arrangement plus the pressure exerted by a pressure spring. The control slide is provided with a throttle flange cooperable with a flow opening in a slide guide whereby the supply of pressure medium to the region in front of the throttle arrangement is regulated depending upon the balance position of the control slide with increasing throttling by excess pressure in the first axial direction. Furthermore, the pressure medium of the system is employed as a remote control medium by effecting a controlled ''''tapping off'''' of pressure medium from the quantity control valve via a remote control valve and an associated single conduit connection to a remotely disposed pressure discharge source. The balance position of the control slide is thus regulated and the supply of pressure medium to the hydraulic component is controlled according to need.

摘要： A hydraulic system for simultaneously operating a plurality of attachments on a motor vehicle, such as a snow plow, dump body, or salt spreader. Separate valves for controlling the attachments are connected in parallel hydraulically between a common pressure manifold and a common return line so that the same pressure is available to each valve. In one embodiment a pressure compensated pump is connected between a fluid reservoir and the pressure manifold. The return line empties fluid into the reservoir. In another embodiment a pressure compensated main pump is connected between the common pressure manifold and the common return manifold to continually circulate fluid under pressure through the system while a priming pump initially charges the hydraulic system with fluid from the reservoir and thereafter maintains a pressurized flooded suction line on the main pump, and supplies make up hydraulic fluid to the system.

摘要： A source of a fluid at a constant pressure is coupled to a manifold and the manifold is coupled to a receiver of the fluid at a constant pressure lower than the source pressure. One of the couplings comprises an orifice having a fixed cross-sectional area. The other coupling comprises a plurality of individually actuatable, digital valve elements. A device that is movable responsive to pressure, such as an actuator for an analog valve plug, is coupled to the manifold. The states of the digital valve elements are controlled by digital signals representative of a command, so the movement of the member is representative of the command. Each digital valve element is designed so its effective orifice area in the open state can be adjusted after assembly. The arrangement is calibrated by individually adjusting the digital valve elements to compensate for the effects of tolerance variations.
