摘要： A master cylinder includes a cylinder housing having a cylinder bore, a seal cup disposed inside the cylinder bore, and a piston slidably disposed in the cylinder bore in sliding contact with the seal cup and defining a pressure chamber in cooperation with the housing and the seal cup. The piston includes a connecting passage which fluidly connects the pressure chamber with an atmospheric pressure chamber when the piston is in a retracted position. The seal cup cuts off fluid communication between the pressure chamber and the atmospheric pressure chamber through the connecting passage when the piston moves in its axial direction by a prescribed distance from its retracted position. The connecting passage is a stepped hole having a first end portion with a small diameter which communicates with the pressure chamber and a second end portion with a large diameter which opens onto an outer peripheral surface of the piston. The cross-sectional area of the first end portion is such as to produce a throttling effect.

摘要： The piston of a master cylinder in the power train of a motor vehicle is made, at least in part, of a thermosetting plastic material and cooperates with one or more annular seals to ensure that a source of hydraulic fluid is communicatively connected with the chamber in the housing of the master cylinder when the piston is moved by one or more springs or otherwise in a sense to increase the volume of the chamber. When a pedal or another actuator causes the piston to expel pressurized fluid from the master cylinder into a slave cylinder, the seal or seals cooperates or cooperate with the housing and/or with the piston of the master cylinder to seal the source from the chamber of the master cylinder. The slave cylinder can actuate the friction clutch between the prime mover and the transmission in the power train of the motor vehicle. The piston of the master cylinder is reciprocable by or with a piston rod by way of a ball and socket joint wherein the ball of the piston rod is held against unintentional extraction from the socket of a connector forming part of or being anchored in the piston.

摘要： A control lever for operating a control system of a vehicle, such as a brake or clutch of a motorcycle, for example. The lever is especially useful with hydraulic control systems, for applying a force to a hydraulic piston of the control system. Preferably, the lever includes an engagement portion that contacts an end surface of the piston. The engagement portion may be free to rotate with respect to a body portion of the lever such that the engagement portion rolls across the end surface of the piston. Such an arrangement provides improved lever “feel” and substantially prevents transverse loading of the piston. The engagement portion may also include a protruding arm that engages the end surface of the piston, for use with hydraulic control systems where the piston is recessed within a housing.

摘要： A master cylinder having a body (10) with a bore (12) therein in which slides at least a primary piston (20). The primary piston (20) has a compensation passage (58), which in a position of rest, places a pressure chamber (24) in communication with a reservoir (14). The communication between interrupted upon actuation of the master cylinder by a control rod (18) acting on a second piston (48) sliding in the bore (12). A first compression spring (28) and a second compression spring (42) urge the primary piston (20) and second spring (16) toward a rear position of rest. The preload force of the first compression spring (28) exceeding that of the second compression spring (16) such that the second piston (48) is the first to move in response to a force applied to the control rod (18). The rear position of rest for the primary piston (200 and second piston (48) is defined by a same stop (36) which is integral with the body (10) of the master cylinder.

摘要： A hydraulic cylinder has a piston (13) with a seal (21) in sealed sliding contact within a bore (12) to define a working chamber (16) ahead of the piston for the discharge of pressurised fluid from the bore via an outlet (17) when the piston is undertaking working stroke, an inlet (20) is provided into the bore from an associated reservoir to allow connection between the reservoir and the working chamber when the piston is in a fully retracted state for recuperation of fluid from the reservoir to the working chamber. The connection between the reservoir and working chamber is provided via a sleeve (27) in the bore (12) winch includes axially extending grooves (28), the grooves being closed by the piston seal (21) during a working stroke of the cylinder but the ends (30) of the grooves being open when the piston (13) is in a fully retracted condition within the sleeve thus by-passing the piston sleeve to connect the working chamber and reservoir. The sleeve (27) may also have a secondary function of providing an abutment (31) for a return spring (32) which returns the piston to its fully retracted position when an operating pedal (14) associated with the piston (13) is released.

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 supplemental nitrous oxide and fuel injection system for use with an internal combustion engine, which includes the unique properties of variable flow-rate control of the supplemental injection system and direct cylinder injection methods. Where an engine is normally controlled by the driver with the (0-100%) throttle control of the existing air/fuel system, this supplemental nitrous oxide and fuel injection system is linked to the existing throttle control and controlled in the same manner. In addition, this system also provides a direct cylinder injection method that completely bypasses the existing intake manifold and carburetor/fuel injection.
