摘要： In a brake fluid pressure boosting device 1 of the present invention, by operation, an input shaft 4 is moves forward to rotate a lever 27 to actuate a control valve 8 so that the control valve 8 produce working fluid pressure corresponding to the input. The working fluid pressure is introduced into the power chamber 6. By this working fluid pressure, the primary piston 37 is actuated to develop master cylinder pressure. On the other hand, the fluid pressure of the power chamber 6 is introduced into the first annular groove 25 of the valve spool 10. By the difference between pressure receiving areas of the first annular groove 25, the valve spool 10 is subjected to rightward force. The position of the pivot of the lever 27 is fixed and the valve spool 10 is controlled in such a manner that the force applied to the valve spool 10 and the spring force of the spool return spring 32 balances with the input, thereby exhibiting the function as a stroke simulator. Because of this function as a stroke simulator, the stroke characteristic on the input side can be changed without affecting the output side.

摘要： The ease of assembly of a radial plunger pump is improved while preventing an external leakage of liquid. A pump housing 2 in the form of a cylinder having a closed bottom contains a pintle 4 therein, which is secured to the bottom of the pump housing 2 by a bolt 6. A rotor 8 is rotatably fitted around the pintle. The rotor is formed with a plurality of radially extending cylinder bores 8a, in each of which a plunger 10 is slidably disposed. A guide ring 16 is disposed around the rotor. A motor 20 is fastened to and secured to the opening of the pump housing, and includes a drive shaft which is connected to the rotor to drive it for rotation. By allowing parts to be assembled into the pump housing in one direction, the ease of assembly is improved while preventing a liquid leakage.
