Abstract: A method of manufacturing a butterfly member of an exhaust brake valve assembly. The method includes providing a metal material, machining the metal material to form a body, and drilling a through bore in a central portion of the body, thereby delimiting a first side of the body from a second side of the body that is opposite the first side. The through bore is configured to receive a shaft for pivoting movement of the body in a valve housing of the exhaust brake valve assembly. The method further includes positioning the body for a single machining operation and machining the body to form a first sealing face on the first side of the body and a second sealing face on the second side of the body. The first sealing face defines a first plane and the second sealing face defines a second plane spaced from the first plane.

Abstract: A valve assembly and a method of assembling a valve assembly. The valve assembly may be an exhaust gas recirculation valve assembly and may include a sealing assembly to inhibit flow of gas from a flow passage into an electronics housing. The sealing assembly includes a first seal along a shaft and disposed between the flow passage and a shaft bearing, a second seal along the shaft and disposed between the shaft bearing and the electronics housing, a plate engaged between a valve housing and the electronics housing, and a sealed bearing supported by the plate and pivotably supporting a pinion. A coolant jacket may be formed in the valve housing around the shaft bore proximate the shaft bearing and the first seal. A butterfly member may be connected to the shaft by a pin rammed into a hole extending through the butterfly member and the driven shaft.

Abstract: An exhaust gas recirculation (EGR) valve assembly includes a valve housing with a wall defining a flow passage. The valve housing defines a bore communicating with the flow passage. A shaft is supported in the bore and extends into the flow passage. A flap is supported on the shaft in the flow passage. The flap is movable relative to the flow passage between a closed position and an open position. A sealing member projects from the wall into the flow path. The sealing member has a sealing surface that interacts with the flap in the closed position to inhibit gas flow through the flow passage, an opposite surface tapering toward the wall, and a circumferential end surface proximate and tapered away from the bore. The flap is coined against the sealing surface. A spider assembly is positioned between the shaft and a drive shaft of an actuator assembly.
