摘要： An anti-skid apparatus for installation in a vehicle braking system having a regulator valve for producing a hydraulic power pressure in accordance with a hydraulic braking pressure from a master cylinder. A control cylinder is disposed in a hydraulic circuit connecting the master cylinder to a wheel brake cylinder, and comprises a cylinder body having a cylinder bore defined therein and a piston axially slidably disposed within the cylinder bore. This piston forms at its one end a pressure chamber communicating with the wheel brake cylinder, and is applied at its the other end with the hydraulic power pressure from the regulator. Disposed in the control cylinder is a normally open cut-off valve which normally permits the flow of the hydraulic braking pressure from the master cylinder into the pressure chamber and blocks the flow of the hydraulic braking pressure when the piston moves to an extent more than a predetermined distance from its initial position for decreasing the volume of the pressure chamber. And, a changeover valve is disposed between the regulator valve and the control cylinder, and applies the hydraulic power pressure to the piston or discharges it from the control cylinder.

摘要： A brake booster includes a body having a central wall portion on which a, doughnut-shaped reinforcement plate is securely mounted, and bolts mounted on the reinforcement plate for fastening a master cylinder to the central wall portion. The reinforcement plate has an annular ridge extending along an inner peripheral edge thereof and projecting against the reinforcement plate. The master cylinder includes a flange mounted on the body and having an inner peripheral portion held against the central wall portion of the body in axial alignment with the annular ridge, and an outer peripheral portion spaced from the central wall portion by a distance such that the outer peripheral portion of the flange will not be forced into contact with the central wall portion when the master cylinder is actuated for braking action. Therefore, no localized forces are applied by the outer peripheral portion of the flange to the central wall portion of the body. The reinforcement plate held in intimate contact with the central wall portion serves to distribute forces fully over the central wall portion, which is less subjected to concentrated stresses and hence can be of a reduced thickness.

摘要： PURPOSE:To simlplify the attachment and detachment of a cap by providing a temporarily tightening projection and the first projection with which the pawl for the skirt section of the cap is hooked and then the second projection spaced at a specified interval with the end face of the skirt section, on the external surface of a reservoir tank opening section. CONSTITUTION:A reservoir tank 14 is carried by hooking each of the pawls 23 of the skirt section 21 of a cap 20 on the temporarily tightending projection 24 of the reservoir tank 14 and temporarily tightening the cap 20 with the tank 14. Since the height of the projection 24 is reduced, the removal of the cap 20 is simple. To seal the tank 24 lafter it is lubricated, each of the pawls 23 to which the cap 20 is pressed down is hooked with the first projection 25. This hooking is elastically performed by the repulsive force of a diaphragm 22 that is inserted between the upper end face of the inner surface of the cap 20 and the opening section 14a of the tank 14 and is compressed. When the cap 20 is removed, the cap 20 can easily be removed by inserting the tip of a tool in the opening end of the skirt section 21 and pushing it upward by using the second projection 26 as a fulcrum.

摘要： PURPOSE:To prevent the unexpected rotation of a handle, by opposing the handle and a plunger to each other so that rotary cam surfaces face each other and by using the force of a spring to push the handle and the plunger toward each other and by keeping the handle and the plunger from being engaged with each other because of the quantity of sliding of the handle based on the cam surfaces. CONSTITUTION:When a handle 11 is pulled rightward, the projection 22b of a locking member 22 is engaged in the notch 20b of a gide member 20 so that the locking member and the guide member can be rotated together. The mutually opposed surfaces 22a, 19a of the locking member 22 and a sleeve 19 are formed as rotary cam surfaces, which act that the handle 11 and a plunger 12 are maintained in prescribed positions relative to each other, by the urging force of a compressed spring 13. The obliqueness of the rotary cam surfaces and the distance between the end face of the locking member 22 and the bottom 20a of the guide member 20 are set so that the locking member and the guide member are not engaged with each other because of the quantity of rightward sliding of the locking member based on the rotary cam surfaces, when the handle 11 is turned.

摘要： PURPOSE:To shorten the total length of the cylinder by a structure wherein the relative sliding stroke of a sealing member between a secondary piston and a cylinder body and the cylinder body and the sliding storke of a sealing member of a primary piston are overlapped with each other. CONSTITUTION:Annular grooves 29 and 31, in which annular seals 32 and 33 are fitted, are formed on the inside of the small diametral part 11b of the stepped cylinder bore 11 of the cylinder body 10. The annular seal 33 slidingly contacts with the outer peripheral surface 13a of the secondary piston 13 in order to cut-off the communication between an annular groove 30 communicating to a reservoir and a first pressure chamber 14. The relative sliding storke l1 of the annular seal 33 and the secondary piston 13 and the sliding storke l2 of the cup seal 19 installed to the primary piston 12 are overlapped partially with each other.
