摘要： A valve control unit for anti-lock and traction control systems for automotive vehicles and valve structures for the valve control unit. The valve control unit has a valve body housing having cylindrical cavities for receiving the internal portion of the valves and a counterbore forming an annular shoulder. Each valve has a radial flange received in the counterbore and seated on the annular shoulder. The periphery of the counterbore is swaged to form an inwardly directed annular lip securing the radial flange in the counterbore. The swaged annular lip also forms a fluid tight seal between the radial lip and the valve body housing. The annular lip is formed by a swaging tool orbited in a rosette pattern. The swaging of the annular lip permits closer spacing between the valves reducing the size and weight of the valve control unit.

摘要： This invention relates to an electro-hydraulic brake-by-wire system including a hydraulic pump and a plurality of valves to achieve a demanded braking force, and to achieve a desired brake pedal feel. The brake system includes a plurality of wheel brakes, a reservoir of hydraulic fluid, and a pump for selectively pumping hydraulic fluid from the reservoir and supplying pressurized hydraulic fluid to the wheel brakes for applying a braking force. The pump acts as a source of pressurized hydraulic fluid to the wheel brakes during normal brake apply, as well as during advanced braking functions as Antilock Braking (ABS), Traction Control (TC), or Vehicle Stability Control (VSC). An apply valve is associated with each of the wheel brakes for selectively permitting flow of pressurized hydraulic fluid from the pump to the associated wheel brake. A dump valve is associated with each of the wheel brakes for selectively permitting flow of pressurized hydraulic fluid from the associated wheel brake to the reservoir. A master cylinder is operated by a brake pedal for pressurizing hydraulic fluid. An isolation valve is associated with each of the wheel brakes for selectively preventing flow of pressurized hydraulic fluid from the master cylinder to the associated wheel brake. A sensor senses the position of the brake pedal and generates a pedal position signal representative of the position of the brake pedal. An electronic control unit receives the pedal position signal, which signal is utilized to determine a brake demand. The electronic control unit controls the operation of the pump, and the apply, dump, and isolation valves associated with each wheel brake to achieve a desired braking force at each wheel brake based on the brake demand and to regulate pressure generated by the master cylinder to achieve a predetermined relationship between the pressure generated by the master cylinder and the position of the brake pedal, whereby a desired pedal feel is achieved.

摘要： A dual master cylinder having a bore of uniform diameter extending through an open end thereof and slidably supporting therein a pair of tandem pistons defining a pair of pressurizing chambers. Fuel input is controlled by center-port poppet valves, and the relative disposition of inlet and outlet brake fluid passages are reversed compared to conventional master cylinders to facilitate master cylinder recession into a vacuum booster without requiring long, angled brake fluid passages and to require a shorter and lighter housing. The inlet and outlet passages are positioned so that seals do not slide over fuel passage ports during operation, eliminating seal wear caused thereby and allowing the ports to be larger, thus reducing back pressure and improving compensation when the pistons are returning to, or are in, an unstroked position.

摘要： The combination isolation and check valve includes a valve member (80, 180) which has a reduced diameter section (82, 182) and an enlarged diameter section (84, 184) disposed in respective bore sections (70, 74) separated by an intermediate diameter bore section (72). The valve member can be displaced by increased fluid pressure to sealingly engage a seal (95) that isolates a master cylinder (12) from an adaptive braking system (10, 120). A flapper valve mechansm (110) that places an rifice (114) at a valve member end opening (96A) communicating with a longitudinal opening (96) and a transverse opening (93). The orifice (114) reduces pressure transmitted from a pump (45) to the bore (22) containing the valve member (80) without restricting fluid flow between the master cylinder (12) and an associated wheel brake (50). The valve mechanism (210) may be disposed in a passage (41) that communicates with the valve member (180).

摘要： A control valve for controlling fluid flow in a hydraulic control unit of a vehicular brake system includes a valve seat. A sleeve is mounted on the valve seat. An armature core is slidably received in the sleeve. The sleeve includes a first ferromagnetic portion adjacent the valve seat, a second ferromagnetic portion, and an annular region defining an area of increased magnetic reluctance. A part of the first portion of the sleeve defines a radial magnetic pole for the generally radial flow of magnetic flux from the armature to the sleeve. A portion of the valve seat adjacent the armature defines an axial magnetic pole for the generally axial flow of magnetic flux from the armature to the valve seat. Together, the generally radial flow of flux and the generally axial flow of flux generate a force urging the armature from an open position toward a closed position when the coil is energized.

摘要： An improved compensation piston arrangement for use with a dual circuit master cylinder having a single service piston for simultaneously pressurizing a first fluid chamber and a second fluid chamber, wherein the compensation piston arrangement provides for pressure balancing between the first fluid chamber and the second fluid chamber to compensate for minor normal differences between the first and second fluid chamber. The compensation piston arrangement includes a movable compensation piston slidably disposed within a bore of a compensation housing, wherein the housing defines a pair of end stops positioned on opposing sides of the compensation piston. The bore is in fluid communication with the fluid chambers such that the pressure within the first fluid chamber acts on a first side of the compensation piston, and the pressure within the second fluid chamber acts on a second end of the compensation piston which is opposite the first end. The compensation housing can be incorporated within the service piston or can be remotely located from the master cylinder.
