  • Patent number: 4762480
    Abstract: Rotary pump comprising a housing having a bore and a first adjacent lateral side wall having at least one inlet slit and a second adjacent lateral side wall having at least one outlet slit of at least equal size to said inlet slit for flow of medium axially therethrough, said slits in said lateral side walls defining the path of flow for said medium from said inlet axially directly into said bore and then from said bore axially directly to said outlet slit, a rotor mounted in the bore for rotation about an axis generally parallel to and eccentric to the bore axis, a plurality of vanes pivotally mounted on the periphery of the rotor having free ends in sliding sealing contact with said bore, each vane having lateral surfaces having an inner edge facing the rotor and an outer edge facing the bore which edges on rotation of the rotor pass over an inner boundary edge of the inlet and outlet slits facing the bore of the housing, said inlet slit and outlet slit, curving along an arc around the rotational axis of ro

  • Patent number: 4621700
    Abstract: Wheel bearing with a built-in homokinetic coupling. The wheel bearing comprises a generally annular inner part, an outer race and two rows of rolling elements located between the outside running surfaces formed on the outer race and the inside running surfaces applied to the inner part. The outer race is equipped with a radially extending flange for the attachment of the bearing. The annular inner part is equipped with a radially extending flange to which the hub of a wheel can be attached. The inner part forms at the same time one unit with the outer ring of the homokinetic coupling. The flange of the inner part is extended with a brake element which forms the part to be braked of a braking mechanism so that the inner part of the bearing, the carrier flange for the wheel, the brake element and the outer ring of the homokinetic coupling form one homogeneous unit.
