  • Publication number: 20020183151
    Abstract: The link belt for power transmission for a continuously variable transmission, with individual links (2) and a ring package (3, 5), which holds the links (2) together, contains an additional, outer ring package (4) for the purpose of absorbing the radial forces generated on the links (2) is provided, which is arranged around the link belt (1) and is mounted such that it can no longer rotate along with the link belt (1), however is still able to follow the strip's adjusting movement, wherein the ring package (5) ensures that the links are guided and held together.

  • Publication number: 20020146327
    Abstract: The radial piston pump possesses a pump body with a plurality of cylinder borings for the reception of pump pistons which can be driven by a cam. The cylinder borings are closed by valve plugs in which pressure passages are provided. In the pressure passages, outlet valves are inserted which respectively possess a valve stem (7) an end of which, proximate to the pump piston (1), is provided with an impact plate.

  • Publication number: 20020136644
    Abstract: The radial piston pump possesses a pump housing in which a plurality of cylinder bores are provided having pump pistons placed therein which can be driven by a cam. Further, an arrangement is provided in each pump piston (3) wherein the inlet or the outlet, or both the inlet as well as the outlet of the fluid in each cylinder bore, is controlled.

  • Publication number: 20020047299
    Abstract: The invention relates to a force deflection device (1) for adapting a lap strap to enhance the comfort of the wearer and optimize the introduction of forces for use by pregnant women and the overweight, comprising a force deflection strap (6) with a first end, which is to be attached to the lap strap, and a second end, which is to be passed through the gap between the seat cushion and the seat back and to be attached to the seat. This second end of the force deflection strap (6) has attached to it a fixing element (2), which is preferably plate-shaped, that cannot pass through said gap in a transverse position relative to the seat. The fixing element (2) can be attached to the rear side of the seat back by means of a hook and loop fastener (3). At its first end, the force deflection strap (6) preferably has a hook (4) and eyes (5) that can be hooked into the latter, allowing it to be looped around the lap strap.

  • Publication number: 20020001525
    Abstract: The invention is based on a radial piston pump (1) with a pump body (2), in which pump body (2) are placed pistons (4), and cylinders (5) arrayed radial to a cam (14) and the pistons (4) upon an inward thrust suck in fluid by means of suction side intakes (17) and upon an outward thrust, the pistons (4) impel fluid through pressure openings (7) in the outer end walls (6) of the cylinder (5) into a plenum (10). It is proposed, that in the base of the cylinders (4) respectively a connection boring (32) is made to the cam (14), which connection boring (32) is controlled by a relief valve (18). Upon the exceeding of its opening pressure the relief valve (18) opens and pressure peaks in the cylinder (5) can be diminished by means of said connection boring. At the same time, a pressure buffer between the base of the piston (4) and the bearing shell (16) is formed.

  • Publication number: 20010048880
    Abstract: The invention is based on a radial piston pump (1) with a pump body (2), in which pump body (2) are placed pistons (4), and cylinders (5) arrayed radial to a cam (14) and the pistons (4) upon an inward thrust suck in fluid by means of suction side intakes (17) and upon an outward thrust, the pistons (4) impel fluid through pressure openings (7) in the outer end walls (6) of the cylinder (5) into a plenum (10) whereby the check valves (22) are formed from an annular coil spring valve (9) which cover the pressure ports (7) and the thereto connected stress relieving corrugations (8), and upon the exceeding of a specified threshold transport pressure, the respective pressure opening (7) opens to the plenum (10). The proposal is made, that a stress relieving zone (27) of a piston-cylinder unit (4, 5) be connected to the pressure zone (5, 7, 26) of a neighboring piston-cylinder unit (4, 5).
