摘要： A gerotor pump is provided with a pump housing defining a chamber and having an inlet and an outlet separated by a planar surface. The planar surface defines a notch connected to the outlet. An inner gear member is rotatably and eccentrically supported within an outer gear member. The inner gear member defines a series of external teeth with a first tooth defining a fluid passage therethrough and a second tooth independent of fluid passages. The fluid passage is defined by an aperture extending axially through the first tooth fluidly connected to a channel extending across the first tooth on an end face of the inner gear member. The passage and the notch cooperate to form a fluid pathway for pressure relief and reduced tonal noise in the pump by disrupting harmonics during operation.

摘要： A vane fluid pump for a vehicle component is provided with an inner rotor supported within a cam. The inner rotor has an outer wall extending between first and second end faces, the outer wall defining a series of slots spaced apart about the outer wall to provide a series of outer wall sections. One of the wall sections defines a groove. Another of the wall sections is independent of grooves or is ungrooved. The pump has vanes positioned within respective slots of the inner rotor and extending outwardly to contact the continuous inner wall of the cam. The groove on the inner rotor is configured fluidly couple with a notch on the housing to provide fluid flow to the discharge port from an upstream pumping chamber to disrupt harmonics during operation to reduce pressure ripples and associated tonal noise.

摘要： A gerotor pump has a pump housing defining a chamber and having a fluid inlet and a fluid outlet. An outer gear member is supported for rotation within the chamber about a first axis, the outer gear member having a series of internal teeth. An inner gear member or inner rotor is rotatably supported within the outer gear member about a second axis spaced apart from the first axis. The inner gear member defining a series of external teeth interposed with a series of external pockets. The inner gear member defines a fluid passage therethrough to fluidly connect two nonadjacent pockets, with another pocket independent of fluid passages. The fluid passage is configured to disrupt harmonics during operation to reduce pressure ripples and associated tonal noise.

摘要： A vane fluid pump for a vehicle component has a cam defining a continuous inner wall surrounding a cavity, and an inner rotor supported within the cam. The inner rotor has a cylindrical outer wall defining a series of slots equally spaced about the outer wall. A series of vanes is provided with each vane positioned within a respective slot of the inner rotor and extending outwardly to contact the continuous inner wall of the cam. Each vane provides a fluid barrier between adjacent pumping chambers formed between the cam and the inner rotor. A first vane of the series of vanes defines a passageway thereacross to fluidly connect adjacent pumping chambers. The passageway is configured to disrupt harmonics during operation to reduce pressure ripples and associated tonal noise. At least another vane is configured without any fluid passageways.

摘要： An engine system is provided with a crankshaft gear coupled to a crankshaft of an engine for rotation therewith, and a balance gear coupled to a balance shaft for rotation therewith. The balance gear and crankshaft gear are in meshed engagement. The balance gear is formed by a series of sectors connected by a series of resilient blocks, with each sector defining first and second recesses along opposite radial edges sized to receive adjacent blocks, respectively. Each elastomeric block is configured to deform both normally and in shear thereby providing damping for the gear. A gear such as the balance gear, and a method of forming the gear are also provided.
