摘要： A tandem type master cylinder for use in a vehicle hydraulic brake system and having a pressure proportioning valve integrally connected thereto includes a piston slidably received in a bore in the master cylinder and defining a pressure chamber at least on one side thereof, and an actuating member or a slide slidable in directions parallel to the piston and having a sensing end and an actuating end projecting respectively from opposite surfaces thereof. The sensing end passes through a slit formed in the circumferential wall of the bore to project into the pressure chamber in the master cylinder. The actuating end cooperates with a valve member of the pressure proportioning valve such that when the piston is displaced beyond a predetermined normal reciprocating stroke the actuating member is slidingly displaced to tilt the valve member, thereby deactivating the pressure proportioning valve.

摘要： An improved and reusable stop assembly is provided for employment in drum brakes of the type having an internal lever operably coupled with the brake shoes for actuating the brake from a standby, partially retracted, relative position of the brake shoes to a position in which the shoes are spread apart to apply braking forces to the drum. The improved stop assembly includes a guide sleeve part mounted on the backing plate of the brake and a freely slideable and removable stop member receivable therewithin. When the stop member is inserted into and locked within the sleeve assembly, its inner end engages the lever to hold the shoes in their standby, partially retracted, relative positions against the forces of yieldably biasing means conventionally coupled with the shoes. The stop member may be released from the sleeve assembly by a simple manual rotation and withdrawal thereof to permit the shoes to shift into a fully retracted relative position facilitating maintenance operations, after which the stop member, which is reusable, may be reinserted into the sleeve assembly and relocked in position to hold the shoes in their standby, partially retracted, relative position by a simple manual reinsertion and rotation of the stop member.

摘要： A deceleration detecting valve for use in a vehicle hydraulic braking system having a master cylinder, a first circuit connecting the master cylinder with front wheel brakes and a second circuit connecting the master cylinder with rear wheel brakes. The valve has a chamber, and a gravity ball received in the chamber and movable from a first position to a second position in receiving a predetermined deceleration thereby restricting the pressure acting on rear wheel brakes. A slidable member is provided in the chamber with one end thereof receiving the pressure in the first circuit, and ball guiding surfaces are defined on the wall of the chamber and on the slidable member. When the first circuit fails the slidable member retracts in the chamber, and a gap is formed between the ball guiding surface on the slidable member and that of the wall of the chamber thereby impeding the movement of the ball.
