摘要： This invention relates to a pneumatically or hydraulically operated hydraulically lapped control apparatus in which a manually operated control valve device supplies a pneumatic or hydraulic fluid under pressure to the larger end of a differential-type abutment that is moved thereby to operate a spring-returned directional valve device. The operation of this device causes the supply of a hydraulic fluid under pressure from a source of supply of such fluid to a device to be operated thereby and to the smaller end of the differential-type abutment until substantially equal fluid pressure forces are obtained on the opposite ends of this abutment whereupon the spring-returned directional valve is rendered effective to cut off further flow of hydraulic fluid to the device to be operated and the smaller end of this abutment. Thus, a hydraulic fluid under pressure is obtained for operating a device and for effecting a self-lapping operation, the degree of this hydraulic pressure being variable in accordance with the ratio of the areas of the opposite ends of a differential-type abutment.
摘要翻译：本发明涉及一种气动或液压操作的液压重叠控制装置，其中手动操作的控制阀装置将压力下的气动或液压流体供应到差速式支座的较大端部，从而使其运动，从而操作弹簧回转方向阀门装置。该装置的操作导致在压力下的液压流体从这样的流体的供应源供应到要由其操作的装置以及差动型邻接的较小端，直到获得基本相等的流体压力该基台的相对端部，弹簧返回的换向阀有效地将液压流体进一步流向要被操作的装置和该基台的较小端部。因此，获得用于操作装置的压力下的液压流体，并且进行自研磨操作，该液压的程度根据差动式支座的相对端的面积的比率而变化。

摘要： A directional valve for controlling an actuator by means of pressurized medium, the directional valve comprising: a spool (4) fitted to move axially inside the directional valve; a first position of the spool (4), in which the spool tends to be set; and a second position of the spool (4), to which the spool can be moved by a pilot control force. In addition to the functions of a directional valve, the directional valve comprises a metering orifice (7) placed in the pressure port (P) or in the first work port (A) or in the second work port (B) or in the tank port (T), and across which a pressure difference is effective. The spool (4) further comprises a second position, to which the spool can be moved by a pilot control force. When the spool (4) is in at least the second position, the directional valve is fitted to generate a compensating force proportional to said pressure difference, to move the spool (4) to compensate for the flow.

摘要： A load independent flow distribution control arrangement for at least two hydraulic users is disclosed, with an adjuster pump, the setting of which is altered depending upon a user load pressure in a repeater line, each user being provided with a proportioning diaphragm with a serial pressure equaliser. Should a load pressure limit for a user be exceeded, the side of the completely pilot-open regulator piston in the pressure equaliser, acting in the closing direction and corresponding to said user, is fed the pressure of the next lowest load user, by means of the above valve arrangement.

A pressure regulating valve (50) is provided that regulates a pressure in a supply/exhaust flow path (10) to a pressure countering against the weight of the body (1) to be conveyed. A switching valve (14) is provided that allows the supply/exhaust flow path (10) and a control flow path (18) to communicate with each other when in balance, and the flow path (10) and a pilot flow path (16) to communicate when in a rise/fall drive. A body (1)-suspending cylinder (2) is attached to a lever member (38) supported on a fulcrum pin (44). A restoring force mechanism (48) for imparting an acting force, in the same direction as that of the load of the body (1), to the lever member (38) is provided in the vicinity of the fulcrum pin (44), and an energizing mechanism (74) for imparting to the lever member (38) an acting force in balance with the weight of the body (1) and with the acting force of the restoring force mechanism (48) is provided. The pressure regulating valve (50) supplies/exhausts compressed air to/from the flow path (10) according to an acting force by the rocking of the lever mechanism (38) and an acting force by the introduction of a pilot pressure from the control flow path (18).

摘要： A fluid system (10) having a directional control valve (12) operated by a pilot valve (11) having a manually operable control handle (22) for selectively controlling a fluid motor (14) in positioning a load (17). The pilot valve (11) includes a spool (31) cooperating with associated portions of the pilot valve to provide a pressure regulated pilot signal to the directional control valve during normal operation of the system. Spool (13) includes a recess (98) which is placed in communication with the high pressure portion of the motor cylinder (16) during a dead engine condition by manipulation of handle (22) to provide pressure regulated delivery of the fluid from the motor (14) through recess (98) and to the conduit normally controlling the directional control valve for effecting a controlled lowering or retraction of the load. A single pilot valve is utilized for effecting the pressure regulated control in both normal and dead engine conditions.

摘要： A hydraulic drive device includes a pump, a hydraulic machine, and a tank. The hydraulic machine is connected fluidically to first and second fluid lines, which are configured to be connected fluidically to the tank or the pump via an adjustable main valve. The device further includes a first valve with a continuously adjustable first orifice. Pressure fluid is configured to be conducted out of the second fluid line via the first orifice and into the tank. The first valve is acted upon in the closing direction of the first orifice by a first spring and acted upon in the opposite direction by the pressure at a control point. The control point is connected fluidically to the tank via a first throttle device, connected via a second throttle device to the first fluid line, and connected to the first fluid line via a third throttle device and a second valve.
