Abstract: A proportioning valve assembly (10, 210) in a housing (12, 212) is pressure responsive to control the flow of fluid to a wheel brake cylinder. The proportioning valve (20, 220) is connected to a fluid channel (31, 231) opening into a reservoir (13, 213), a second valve (34, 234) being disposed in the channel (31, 231) and being engaged by an inertia sensitive ball (40, 240) located either on a ramp (17) or within a recess (235) of the second valve (234). The ball (40) is responsive to deceleration of the vehicle and moves up the ramp (17), or the ball (240) moves multi-directionally from the recess (235) to be both longitudinal and lateral deceleration responsive. Movement of the ball (40, 240) permits the second valve (34, 234) to close and prevent fluid communication between the fluid reservoir (13, 213) and the proportioning valve (20, 220) in order to vary the outlet pressure of the proportioning valve (20, 220) in response to deceleration or cornering of the vehicle. The proportioning valve (20, 220) includes a second piston (80, 280) which has a plunger end (82, 282) that extends within the channel (31, 231) and a bore (303) of a sleeve (301). The sleeve (301) has an orifice (307) to restrict fluid pressure flow from the bore (303) around the plunger end (282) and through the orifice (107, 307) to the channel (31, 231). The sleeve (301), orifice (307), and plunger end (82, 282) provide damping of second piston when sudden high pressure applications occur, and thereby eliminate the occurrence of wheel lock-up.

The rotor (30) and pintle (40) are disposed within a pumping bore (18) that is eccentrically aligned relative to bore extensions (28) receiving the pintle (40). The rotor (30) is driven by an offset motor (12) which engages a periphery of the rotor (30). The pintle (40) has therein two pairs of longitudinal passages comprising supply (46, 53) and discharge (47, 54) channels which communicate with respective intake (41, 43) and exhaust (42, 44) ports within the pump housing (16). The rotor (30) has sets of axially offset pistons (90, 100) received within piston cavities (93, 93'). Each set of piston (90, 100) comprises a metal piston cap (95) having a central opening (90) which receives a longitudinal extension (97) of a piston sealing ring (98). Each piston sealing ring (98) has an opening (111) extending into the longitudinal extension (97) in order to house a spring which engages a recess (34) of the piston cavity (93) to bias the piston outwardly into engagement with a bearing mechanism (70) disposed within the pumping bore (18). Each piston cavity (93, 93') has an end opening (94, 94') communicating intermittently with the associated supply (46, 53) and discharge (47, 54) channels as the rotor (30) rotates about the pintle (40). The pump (10) provides a dual channel pumping function with as many pistons as desired for each channel.

Abstract: A hydraulic brake booster includes a spool valve within a housing for communicating fluid pressure into a chamber for urging a piston in a direction actuating a master cylinder, thereby effecting a brake application. The communication between an inlet passage and the chamber is regulated by a land on the spool valve cooperating with a corresponding land on the housing. In order to prevent particles which are carried in the pressurized fluid from wedging in the interface between the land and the corresponding housing land, an additional land is provided on the spool valve. The additional land cooperates with another land on the housing to form a small clearance therebetween so that large particles in the fluid are prevented from wedging in the interface between the sensitive land and the corresponding land on the housing when the valve is in the brake-released position.

Abstract: A hydraulic brake booster includes a housing 12 with a first chamber 40 and a second chamber 42. An input member 54 extends into the first chamber 40 and is exposed to the second chamber 42. The input member is movable within the first chamber 40 to increase fluid pressure within the second chamber 42 and this fluid pressure operates a control valve 90 to communicate fluid pressure to the first chamber 40. The fluid pressure in the first chamber 40 acts against the input to bias the same toward the second chamber 42. An output member 70 is movable in response to the fluid pressure within the second pressure chamber 42 to actuate braking.

The piston encloses a storage chamber and forms a passage communicating the storage chamber with the pressure chamber. A valve member is disposed within the passage to control communication between the storage chamber and the pressure chamber. An operator actuator cooperates with a control valve to communicate pressurized fluid to the pressure chamber and a finger is actuated by the operator actuator to engage the valve member, thereby opening communication between the storage chamber and the pressure chamber. The valve member comprises a unitary assembly having a sleeve sealingly engaging the wall of the piston passage, a seat member biased into engagement with a shoulder defined by a stepped bore on the sleeve, and a stem extending through a bore on the seat member.
