Claims (1)

[Scope of utility model registration request] In a hydraulic clutch release device comprising a master cylinder device driven by operation of a clutch pedal, and a slave cylinder device driven by hydraulic pressure from the master cylinder device to connect and disconnect the clutch, the hydraulic clutch of the master cylinder device A liquid conduit that communicates between the chamber and the liquid chamber of the slave cylinder device is closed at both ends in the axial direction and has a liquid inlet and outlet formed in a closed portion on one end, which connects the master cylinder to the master cylinder through the liquid conduit. A cylindrical casing is interposed which communicates with the liquid chamber of the device and has a liquid inlet and outlet formed in a closed portion at the other end that communicates with the liquid chamber of the slave cylinder device via the liquid pipe line. A piston is provided inside the casing and has a large diameter portion that slidably abuts on the inner periphery of the casing, and the piston is interposed between the large diameter portion on one end side of the piston and the closed portion on the one end side of the casing. a first spring that biases the spring toward the other end;
a second spring that is interposed between a large diameter portion on the other end side of the piston and a closed portion on the other end side of the casing and biases the piston toward the one end side; A cylindrical weight that loosely fits on the outer periphery and whose outer periphery fits loosely on the inner periphery of the casing, and a weight that is interposed between one end of the weight and a large diameter portion on one end side of the piston. a third spring that urges the weight toward the other end; and a fourth spring that is interposed between the other end of the weight and the large diameter portion of the other end of the piston and urges the weight toward the one end. a spring, the first fluid chamber having a spring disposed at one end of the piston communicates a first fluid chamber in which the first spring is interposed with a third fluid chamber in which the third spring is interposed; A communication path is formed, and the second liquid chamber in which the second spring is interposed and the fourth liquid chamber in which the fourth spring is interposed communicate with each other at the other end of the piston. 2
a first check valve that allows liquid to pass only from the fourth liquid chamber side to the second liquid chamber side is interposed in the second communication passage; A third communication path is formed in the casing to communicate the second liquid chamber and the fourth liquid chamber, and the fourth liquid is introduced into the third communication path from the second liquid chamber side. A hydraulic clutch release device characterized in that a second check valve and an orifice are interposed to allow liquid to pass only to the chamber side.
