摘要： A valve arrangement, which possesses a plurality of valve units mounted on each other in sequence in an array direction (3) on each other. For this purpose each valve unit (2) possesses, on opposite sides, a first mounting face (5) and a second mounting face (6). In the interior of each valve unit (2) there extends, in a direction athwart the array direction (3), at least one internal flow duct (32a and 32b). On its longitudinal side, facing the first mounting face (5), same is delimited by a lateral duct wall (36a and 36b) of the respective valve unit (2). On the opposite longitudinal side it is at least partially open, the open length section (37a and 37b) being covered by the mounted neighboring valve unit. Accordingly compact width dimensions are possible.

摘要： A valve assembly has a single piece body that houses a plurality of hydraulic valves. Each valve includes a spool which controls the flow of fluid between a pair of work ports in one side of the body and a pump inlet and a tank outlet. The valves are operated by selectively applying pressurized fluid to one end or the other of the spool. That pressure is provided by a conduit or a pilot valve that is attached to a control port in the one side of the body. Because the majority of the connections to the valve assembly are made to the one side of the body access is only required to that side.

摘要： A switching device for a machine, especially a digger, has at least one supply connection and one useful connection in addition to at least one hydraulic accumulator. An on-off valve is arranged between the supply connection and the useful connection, and separates the supply connection at least partially from the useful connection in one of its switching positions, in addition to ensuring that the hydraulic accumulator is charged on the fluid side via the supply connection. In another switching position, the supply connection is connected to the useful connection. A substantial improvement relative to conventional switching devices is attained by being able to guarantee an emergency function before the machine is used to perform work.

摘要： A dual-spool hydraulic directional valve for controlling the motion of a hydraulic cylinder or similar device. The dual-spool hydraulic directional valve of the present invention is less costly to manufacture, may be more easily repaired, and is more resistant to contamination than current hydraulic directional valves. The dual-spool hydraulic directional valve of the present invention is particularly suited to applications where the valve is not required to hold a load. The valve of the present invention uses two valve spools, with each valve spool controlling flow of hydraulic fluid through a particular port or ports. The valve spools work independently from one another, therefore, the slight leakage of hydraulic fluid from one valve spool to the other will not markedly affect the operation of the valve. In a preferred embodiment of the valve, a lever is utilized to shift the positions of the respective valve spools, although other means, such as electronic solenoids may also be used.

摘要： A multiple valve apparatus is formed of a priority valve mechanism for dividing an operating liquid into a priority flow and a surplus flow, at least one switching valve mechanism attached to the priority valve mechanism, a parallel line for guiding the surplus flow discharged from the priority valve mechanism to an input port of the at least one switching valve mechanism, a tank line for discharging the operating liquid to a tank, and an urgent valve situated between the parallel line and the tank line. The urgent valve is operated in a predetermined condition to regulate an operation actuated by the surplus flow through the at least one switching valve mechanism. Therefore, the supply of the operating fluid only to the switching mechanism can be stopped or regulated by this simple structure, and an automatic stop or regulating function of an actuator can be achieved in the apparatus.
