Abstract: A hydraulic motor pump unit for pressurising a hydraulic fluid in a hydraulic circuit. The motor pump unit includes a motor having a motor stator holding a circular array of coils and a motor rotor having a motor rotor body having an outer circumferential rotor surface holding a circular array of magnets. The motor rotor body is positioned within the motor stator holding the magnets opposite the coils. A pump is drivable connected to the motor rotor. A housing body provided with a pump chamber for housing the pump and a cylindrically shaped coil support for supporting the circular array of coils. The housing comprises at least one housing end cap which is connected to the coil support which housing end cap is provided with a fin pattern for an air cooling of the housing to an environment.

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: 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.

Abstract: A cap assembly for a container and a method of assembly. The cap assembly includes a housing couplable to a container opening, the housing defining a housing opening communicating with the container opening; a cover operable to close the housing opening; and a retainer mechanism operable to releasably connect the cover to the housing, the retainer mechanism including a non-fusible member selectively contacting the cover and the housing, and a fusible member operable to hold the non-fusible member in contact with the cover and the housing in a retaining condition, the fusible member deforming at or above a threshold of the condition to allow the non-fusible member to move out of contact with one of the cover and the housing, in a release condition, to open the container opening to atmosphere.

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: Pump unit (10) comprising an electrically driven hydraulic pump (4) for pressurising a hydraulic actuating system. The pump unit (10) comprises a hydraulic pump (4) in pump chamber (110) of a pump housing (11). The pump (4) is driven by an electric motor (3) which includes a motor rotor body (310) and an assembly of field coils (32) and magnets (33). A clearance (C) is provided around the motor rotor body (310) which is diverging in the axial direction from a small to a large diameter, such that a rotation of the motor rotor body (310) forces hydraulic fluid to flow towards the larger diameter. The fluid outlet (122) at the larger diameter of the clearance allows an exit of the hydraulic fluid, such that a fluid flow is generated which reduces hydraulic friction inside the pump unit to render an increase in pump capacity.
