    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: A screw compressor (10) comprises a housing (12, 14, 16), a slide valve assembly (23) and a pulsation damper. The housing (12, 14, 16) receives a supply of working matter from a pair of intermeshing screw rotors (18, 20), and comprises a slide recess (51), a pressure pocket (32), and a piston cylinder (54). The slide valve assembly (23) regulates the capacity of the screw compressor (10), and comprises a slide valve (36) axially movable within the slide recess (51) and the pressure pocket (32), a piston head (40) axially movable within the piston cylinder (54), and a piston shaft (38) connecting the slide valve (36) with the piston head (40). The pulsation damper comprises a flange (58) for separating the pressure pocket (32) from the piston cylinder (54), a bore (60) for receiving the piston rod (38), and a damping channel (46A) extending through the flange (58).

    摘要: The vane pump includes a housing enclosing the rotor and vanes, the housing including an inner surface defined by a core profile to cause the vanes to extend and retract radially to provide a predetermined vane displacement with rotation of the vanes. The core profile includes an inlet profile portion and an outlet profile portion, wherein the core profile includes a vane radius modifying portion defined between the inlet profile portion and the outlet profile portion such that a radial extension of a vane that is guided along the inner surface will change when transiting the vane radius modifying portion.

    摘要: A muffler is disclosed. In the muffler a throttling device that is controlled by the energy of the airflow to be muffled is provided in a pipeline of the airflow that needs to be muffled. The muffler is adjusted by itself according to random variety of the pulsing airflow, and can eliminate or reduce effectively the pulsation of the airflow and the related noise in the range of the low frequency and the middle frequency. The muffling effect of the muffler has no correlation with the volume of the muffler, and therefore the volume of the muffler can be reduced.

    摘要: A variable displacement pump includes a pump structural member configured to change volumes of a plurality of working chambers by rotation of a rotor, so as to introduce oil through an inlet port into the working chambers and to discharge the oil through a discharge port, and further configured to oscillate a cam ring by a discharge pressure introduced into a control oil chamber. A first coil spring is provided to force the cam ring in a direction for increasing of a rate of change of the working-chamber volume. A second coil spring is provided to force the cam ring in a direction for decreasing of the rate of change of the working-chamber volume. The first and second coil springs are laid out on both sides of an arm portion of the cam ring in a manner so as to be opposed to each other.
