Abstract
PURPOSE: To effectively prevent vibration generated in the case when controlling this machine, by mounting a by-path valve, which opens when signals related to the acceleration of load reach value not less than a fixed level, between the inflow and outflow ports of an actuator.
CONSTITUTION: When the output signals 9a of an accelerometer 9, to which load 1 is installed, vary over a range not less than fixed value, control signals 10a are fed to a by-path valve 8, and the by-path valve 8 is opened. Thus, vibration generated in the case when controlling this oil pressure machine can effectively by prevented, and shock acting on the oil pressure machne can be reduced.
