IPC: F15B11/02
Filed: 1988-11-22
Abstract: PURPOSE:To improve operational performance by switching a capacity control valve from a large-capacity to small-capacity, and vice versa, corresponding to the output from a detecting switch, which detects the operational force, if any, at the full-strode position of a control lever. CONSTITUTION:When an operator operates a control lever 23 of a hydraulic shovel or the like, pressure of a pressure reducing valve 25A or 25B is set via a pusher 24, while the direction of a direction switching valve 11 is switched to drive a hydraulic motor.
