摘要： Provided is a hollow rotor and method for making a hollow rotor for a gerotor system, the gerotor system including inner and outer rotors having interengaging lobed profiles. At least one of the inner or outer rotors comprises the hollow rotor, the hollow rotor including radially inner and outer walls radially spaced-apart in relation to a rotational axis of the rotor and walls extending between the radially inner and outer walls for closing axial ends of the hollow rotor. The radially inner and outer walls define therebetween a cavity, thus providing for a hollow or empty interior of the hollow rotor. At least one of the radially inner or outer walls forms a plurality of lobes circumferentially spaced-apart around the cavity.

摘要： This invention provides both a pump and a lubrication and cooling system with a pump which includes a pump housing, a rotor, a relief valve and a bypass valve. The relief valve is configured to relieve pump pressure when the pump pressure is indicative of an abnormal restriction of flow. The bypass valve is configured to direct fluid flow from an outlet chamber of the pump to an intake chamber of the pump when pressure in the outlet chamber is at a value associated with a predetermined speed of rotor rotation.

摘要： An object is to avoid generation of a collision sound of a second vane of a compression system comprising a multicylinder rotary compressor being configured to be used by switching of a first operation mode in which both rotary compression elements perform a compression work and a the second operation mode in which the only first rotary compression element substantially performs the compression work. When the second operation mode is switched to the first operation mode, discharge-side pressures of both the rotary compression elements are applied as a back pressure of the second vane, and thereafter an intermediate pressure is applied which is between suction-side and discharge-side pressures of both the rotary compression elements. When the first operation mode is switched to the second operation mode, a valve device interrupts flowing of a refrigerant into a second cylinder, and thereafter suction-side pressures of both the rotary compression elements are applied as the back pressure of the second vane.

摘要： A sealing ring is provided between an end plate of an eccentric rotation body and a support plate so that a pressure of fluid at high pressure is allowed to work on the end plate, thereby allowing an axial-direction pressing force to work on the end plate. The sealing ring is arranged eccentrically away from the a center of a cylinder as forming the eccentric rotation body to minimize separation of the axial-direction pressing force from a thrust load in the a radial direction in the end plate of, thereby reducing turnover moment effectively.

摘要： The current invention has as objective to complete our works relative to motor machines by generalizing certain support methods, such as that by poly inductive mechanics, by hoop gear, as well as generalizing the realization criteria of motor machines, showing mainly that the degrees of mechanic rotativity of them can be realized horizontally, thus assuring the realization of machines said rotativo-circular, with differential or contrario dynamics, these machines allow to complete the chromatic ranges of motor machines and to differentiate the levels of dynamism, and their material figuration degrees, both real and virtual. We'll show in addition that the mechanical generalizations correspond to the dynamic generalizations of the figures.
