Title: Load response type hydraulic pressure control valve
Inventor: TAKIMOTO TADAO
IPC: B60T8/28
Filed: 1982-02-18
Abstract: PURPOSE:To prevent both the change of the split hydraulic pressure caused by the response delay of an insertia valva and any delay of the start of hydraulic pressure control into the rear wheel cylinder, by increasing the pressure receiving area of an actuator piston for a load response type hydrualic pressure control valve, when this piston is moved. CONSTITUTION:When the hydraulic pressure P1 from a master cylinder is raised, this hydraulic pressure P1 is made to act on an actuator piston 10 through a throttle 3. The piston 10 has the pressure receiving area of S2 due to the contact of the annular protrusion 14 of a cap seal 13. When the force caused by the hydraulic pressure rise that is applied to this pressure receiving area S2 overcomes the spring force of a dummy spring 9, the piston 10 moved right against the spring 9 and releases the sealing caused by the annular protrusion 14 of the cap seal and then increases the pressure receiving area from S2, S1 that is determined by a cylinder hole 12. As a result of this increase, the hydraulic pressure that is almost equal to that of the master cylinder when the movement of an inertia valve 1 is started, is always sealed in the piston 10 and the split hydraulic pressure that starts pressure reduction control can be thus accurately set.
