    摘要: A master cylinder includes a cylinder, a piston slidably provided in the cylinder, an annular cup seal held on an inner circumferential surface of the cylinder, and a relief port formed in the piston. The piston and the cylinder define a pressure chamber for generating fluid pressure in front of the piston, and the cylinder and an outer circumferential surface of the piston define a fluid supply chamber which communicates with a reservoir. The cup seal is adapted to slide against the outer circumferential surface of the piston to separate the fluid supply chamber from the pressure chamber. The relief port provides communication between the pressure chamber and the fluid supply chamber. A control taper surface is formed on the outer circumferential surface of the piston rearwardly from the relief port. The control taper surface is tapered toward the front of the piston and is capable of abutting against an inner circumferential surface of the cup seal.

    摘要: A plunger moved with an input shaft is movably fitted in an axial bore of a valve body made of resin, and a valve mechanism selectively establishes and cuts off communication in a negative pressure passage and an atmosphere passage formed in the valve body according to the movement of the plunger. Also, a pair of radial holes formed to have a circular cross section are provided in the valve body by drilling work, and a plate type stop key formed in a fork shape having two claw branches is mounted by loosely inserting the branches in the radial holes. The stop key limits a movement range of the plunger. Also, a guide portion is formed on an outer circumference of the valve body to guide side surfaces of the stop key. The movement of the stop key is restricted by the guide portion and a step formed in the axial bore of the valve body. Therefore, a smooth operation of the pneumatic booster can be guaranteed.

    摘要: There is disclosed a pneumatic booster having a vacuum chamber connected to an intake pipe of an engine. An air outlet of an ejector is connected to the intake pipe through a vacuum control valve, and an air inlet of the ejector is connected to an air cleaner. A vacuum pick-up port of the ejector is connected to the vacuum chamber of a booster body. The vacuum control valve comprises a control chamber and a control piston, and the negative pressure in the booster is introduced into the control chamber and acts on the control piston. When the negative pressure in the booster is insufficient, the control piston acts to open the control valve and a negative pressure is supplied from the ejector to the vacuum chamber. When the negative pressure in the booster is sufficiently high, the control piston acts to close the control valve and stops the operation of the ejector, thus reducing an effect of the ejector with respect to an air/fuel ratio of the engine.
