摘要： A vacuum type brake booster device comprising a booster shell divided into front and rear halves, a booster piston accommodated in the booster shell, and tie rods extending through the booster piston for connection of the front and rear halves. The tie rod is firmly held upright at a prescribed position on the rear half wall by the combined action of a mounting support on the rear half wall, a stepped tie rod flange, an elastic sealing member disposed in said mounting support between the rear half wall and the stepped flange, a retainer ring inside the mounting support. Accordingly, the tie rod thus firmly secured to the rear half is readily aligned with and pass through a through hole in the front half to expedite the assembly of the front and rear halves and, in addition, use of the elastic sealing member contributes to the simplification of the construction.

摘要： A highly durable and light-weighted vacuum type brake booster device including a booster shell, a booster piston axially slidably accommodated in the booster shell to divide the interior thereof into a first chamber communicating with a vacuum source and a second chamber adapted to be placed into selective communication through a control valve with the first chamber and the atmosphere, and an input rod operatively connected with the control valve for operating the latter to generate a pressure differential between the first and second chambers. The front and rear walls of the booster shell are connected with each other by means of tie rod(s) which extend(s) through the booster piston with a deformable seal member disposed therebetween. The booster piston is urged in a retracting direction by a return spring disposed in the first chamber. A retainer plate for supporting one end of the return spring abuts against the front wall of the booster shell to prevent the vacuum deformation thereof and is secured to the tie rod so that the resilient force of the spring is shared by the tie rod to avoid any excessive loading on the booster shell.

摘要： A master cylinder-reducing valve assembly has a master cylinder and a reducing valve for transmitting output hydraulic pressure from the master cylinder to a rear wheel brake at a reduced level. The reducing valve includes a valve housing provided on the master cylinder and having an inlet communicating with the output port of the master cylinder and an outlet communicating with a rear wheel brake. A pressure receiving piston is slidably received in the valve housing to divide the interior of the housing into an input hydraulic chamber communicating with the inlet and an output hydraulic chamber communicating with the outlet. The pressure receiving piston has a communication bore connecting between the input and output hydraulic chambers. A valve member is disposed in the input hydraulic chamber to open and close the communication bore. A valve spring is received in the valve housing and biases the valve member toward the pressure receiving piston. A pressure regulatng spring is also received in the valve housing for biasing the pressure receiving piston away from the valve member. The valve housing comprises a first half part having the inlet and integral with the master cylinder, and a second half part having the outlet and screwed to the first half part. The second half part has a valve cylinder fitted into its opening adjacent the first half part. A valve cylinder houses the valve member and the valve spring loaded between the valve member and the valve cylinder.

摘要： A vacuum type brake booster device comprising a booster shell, a booster piston accommodated in the booster shell, a piston diaphragm working together with the booster piston for dividing the booster shell into both front and rear working chambers, and tie rods extending through the piston and the diaphragm for connection of the front and rear walls of the booster shell. Circumferential positioning devices are arranged between the booster piston and piston diaphragm and between the piston diaphragm and booster shell, respectively, so that the piston can correctly be adapted to the shell. Accordingly, the booster piston can be operated freely from interference of the tie rods. Furthermore, the piston diaphragm can be prevented from unnecessary forces due to the pressure difference between both the working chambers by the aid of thin-wall portions arranged in the piston diaphragm.

摘要： On the wall of a booster shell which defines a vacuum chamber, a nonreturn-valve casing is formed in two halves. One casing half is formed integral with the wall of the booster shell and the other casing half is rotatably fitted to the former. With the first casing half formed in effect as a part of the wall of the booster shell, there is no leakage of vacuum from the booster shell to the exterior thereof. The second casing half has an L-shaped connector pipe formed integral therewith for connection with a vacuum line and the bent tip portion of the L-shaped connector pipe can be set in any radial direction simply by adjusting the angular position of the second casing half relative to the first.
