Abstract

PURPOSE: To stabilize the brake pedal stroke in a captioned cylinder by closing a nonreturn valve for intercepting the connection between the first pressure chamber and a reservior for operating a piston and opening the nonreturn valve mechanically and forcedly for returning the piston to a normal position.
CONSTITUTION: A nonreturn valve 17 to permit the introduction of liquid from a reservoir 16 to the first pressure chamber 7 and a relief valve 18 to provide for the upper limit value of pressure are equipped in a connecting port 1c of a master cylinder to be used for a hydrostatic brake device for a car. Normally, the first pressure chamber 7 is connected with the reservoir 16, as a small diameter part 2b of a piston 2 is pushed to a control member 27 and a support body 21 and a valve body 20 of the nonreturn valve 17 are inclined round the support of a contact point A for giving a gap between the seal operation part of the valve body 20 and a valve seat 19. For operating a brake, the nonreturn valve 17 is closed to increase the pressure in the first pressure chamber 7 by a stable pedal stroke. For releasing the brake, the nonreturn valve 17 is forcedly opened, and necessary braking liquid is introduced into the first pressure chamber 7 for obtaining an effective control.
