Three-way flow regulation device e.g. for excavator or fork lift truck hydraulic system with flow regulating plate provided by pressure balance acted on by pressure dependent on measured flow

摘要

The flow regulation device (1) has a flow measuring plate (3) and a parallel flow regulating plate (4) downstream of the flow measuring plate, provided by a pressure balance (7) with a blocking position (7a) and a through-flow position (7b), acted on by a spring (9) and a pressure which is dependent on the measured flow.
