ABSTRACT:
An air bleeder is disclosed for a fluid system such as a braking liquid pressure control valve which operates to reduce a braking liquid pressure supplied to a rear wheel cylinder at a given proportion to a braking liquid pressure supplied to a front wheel cylinder as a braking liquid pressure is supplied from a master cylinder. An air bleeder is disposed for use with such a fluid system, in particular, with a fluid system in which a plunger is slidably received in a bore formed in a housing in which a plate is fitted to serve as a stop member and an end of the plunger is maintained in abutment against the plate when it is inoperative. A space which is defined between the periphery of the plunger in the region of its end and the internal surface of the bore and which communicates with a fluid passage extending through the plunger and the plate is sealed against an exterior by a seal member. The air bleeder comprises an air bleeding path formed in the plate so as to extend across the area of contact between the plate and the plunger to maintain the space in communication with the fluid passage. In this manner, a satisfactory air bleeding from the space is assured.
