摘要:
A hydraulic directional-control valve comprises a first inlet part, a second inlet part, a tank port, a work part and a valve member which is movable from a neutral position to a operating position. In the neutral position, the valve member connects the first inlet port with the tank port and blocks the second inlet port. In the operating position, it blocks the first inlet port and connects the second inlet port with the work port. A third inlet port is provided and the valve member in the neutral position blocks the third inlet port and in the operating position connects it with the work port. The third inlet port may be supplied with hydraulic fluid in parallel with the second inlet port when an additional fluid flow is required.
