摘要： A system for handling gates and the like including a dual-effect hydraulic actuator with a stem traversing one of its chambers and a supply circuit controlled with oil which alternately moves the oil between the actuator chambers for an ‘opening’ or ‘closing’ movement. The circuit includes a pump for transfer of the oil between the chambers through piloted locking one-way valves, an oil tank and two one-way suction valves each connected between the tank and one of the two sides of the pump for allowing suction from the tank of the lacking oil. The suction valve connected from the side of the pump opposite the actuator chamber not traversed by the stem is a one-way valve controlled in such a manner as to open thanks to an overpressure on the hydraulic circuit branch which is for supply of the actuator chamber traversed by the stem. In this manner the oil in excess during movement of the actuator which is caused by transfer of the oil from the stemless chamber to the chamber with stem is dumped into the tank.

摘要： A closed-circuit pump is provided that receives input from a steering unit in order to drive a steering cylinder. The closed-circuit pump is preferably a proportional bi-directional pump. The steering unit includes a steering wheel or similar device controlled by an operator. In one embodiment, the steering unit is a conventional hydraulic system that includes a servo pump. In another embodiment, the steering unit is an electronic displacement control system. The steering cylinder engages with a steering assembly to perform the steering function by physically turning the wheels of the vehicle. The inlet of the steering cylinder includes a counterbalance valve, which prevents flow into the steering cylinder when there is no steering input from the operator.

摘要： In an hydraulic operating arrangement the working chambers (3, 4) of a double-acting working cylinder (1) are connected respectively by way of one reciprocally unlockable check valve (8, 9) with respectively one side of a reversible pressure medium source (11). The respective working chamber (3, 4) under pressure is connected with a joint, controllable proportional pressure regulating valve (15) for pressure control. On its exit side the proportional pressure regulating valve is connected with the pressure medium lines (6, 7) by way of respectively one check valve (18, 19) that opens in the direction of the pressure medium lines (6, 7), in particular between the corresponding unlockable check valves (8, 9) and the respectively belonging working chamber (3, 4) of the working cylinder (1). This way the system pressure is easily controlled by way of the proportional pressure regulating valve, and the pressure medium that is directed away is returned from the exit side of the proportional pressure regulating valve (15) directly to the pressure medium cycle and to the aspirating side of the working cylinder, thus making a simple apparatus and safe operation possible.

摘要： This invention relates to a valve device for at least one hydraulic motor adapted to drive a high inertia mass. The device comprises two principal conduits, respectively intended to be connected to the two principal ducts (supply or exhaust) of the motor. It comprises a communication conduit for placing said principal conduits in situation of communication when the fluid pressures in these conduits are substantially equal and for placing said principal conduits in a situation of isolation in which they are isolated from one another when the fluid pressures in these two conduits are different. The device further comprises delaying means adapted to limit the speed of passage between the situation of communication and the situation of isolation. The communication conduit may include a calibrated restriction. Similarly, the delaying means may include calibrated restrictions.

A hydraulic system having different modes of operation is provided for the operation of the piston/cylinder arrangements. The hydraulic system can operate in a normal mode for raising or lowering the yoke and in other modes by interconnecting upper and lower chambers of the piston/cylinder arrangements and utilizing a differential surface area of the piston exposed to the two chambers for rapidly raising or lowering the yoke.

摘要： An engine/pump control device for loaders is disclosed. The control device controllably distributes the output power (rotating force) of an engine to the travelling and working units of a loader in accordance with operational conditions of the loader, thus remarkably improving work efficiency of the loader. When the loader performs an operation requiring a high tractive force prior to the driving force of the working members, the control device opens the unloading valve thereby partially returning the output fluid of a hydraulic pump to a return tank while transmitting the surplus output power of the engine to the traveling unit. Meanwhile, when the loader performs an operation requiring a high driving force of the working members prior to the tractive force, the control device closes the unloading valve, thereby totally supplying the output fluid of the hydraulic pump to the actuators in order to generate a high moving speed of the working members.

摘要： A purification apparatus for removing gases and water from a fluid in a system, including a tank which has an expansion chamber for fluid in the system. A pump pumps the fluid in a circulation circuit of which the purification apparatus is an integral part. A closed chamber has a fluid-free upper part and contains a level-sensing device which controls flow of fluid to the closed chamber. The fluid-free upper part of the closed chamber is connected with a vacuum pump which sucks gases from the closed chamber and creates a lower pressure in the closed chamber than at an outlet of the apparatus. A pressure-generating device sucks fluid from the closed chamber.
