Abstract
A fluid-pressure pumprotated by an electric motordrives a fluid-pressure cylinder. A discharge flow restrictoris provided in a discharge passagethrough which a working fluid from the fluid-pressure pumpis supplied to fluid-pressure cylinder. A pilot-pressure-operated shut-off valvechanges over a connecting position A at which the discharge passagebetween the discharge flow restrictorand the fluid-pressure cylinderis connected to the tankand a shut-off position B at which the discharge passageis disconnected from the tank, in response to a pressure Pin the discharge passagebetween the discharge flow restrictorand the discharge port, thereby enabling a change-over between a loaded mode and an unloaded mode assumed at an fluid-pressure actuator unitin response to an operation of the fluid-pressure pump
