Abstract
A remote compensation valve (20) through which pressurized fluid from a master cylinder (14) is communicated to the wheel brakes (24, 26) of a vehicle. The compensation valve (20) has a housing (200) with a bore (202) therein for retaining a shuttle piston (210). The shuttle piston (210) has a first land (212) separated from a second land (214) by a groove (216) and an axial bore (218) connected to the groove (216) by a radial bore (224). A first spring (250) carried by the piston (210) urges a poppet valve (244) toward a seat (230) to control the communication of pressurized fluid through the axial bore (218) to an outlet port. A second spring (254) located in the housing (200) urges the piston (210) toward a rest position where the first land (212) engages a pin (234) of a tilt valve (232) to establish communication between the source of fluid and the bore (202) and the poppet valve (244) is seated on the piston (210) to prevent communication through the axial bore (218). A manual input force on a first end (262) of a movable stop pin (250) brings a second end (266) into engagement with the poppet valve (244) to initiate communication between the compensation port (206) and the master cylinder (14) to remove any air from the master cylinder (14).
