Hydraulic pressure reservoir connecting valve block has connectors for coupling reservoir tank with three way valve formed as ball with fixed control shaft

摘要

The hydraulic pressure reservoir connecting valve block has connectors (S, P, T) for coupling a reservoir tank (2) to a hydraulic pump (11). The block has a three-way valve (8) for the reservoir. The closure (9) of the valve is formed as a ball with a centrally fixed control shaft (17). The bore opening circumferential surface of each passage has a seal (D1-3).
