  • Patent number: 4679537
    Abstract: A damping device is proposed, which serves to equalize and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damping device includes a damper element which has at least one damper diaphragm fastened in a damper housing and is arranged to define a fuel chamber which communicates via a feed pipe with a fuel distributor line. The feed pipe is oriented toward a flow tube which communicates with a fuel supply line and protrudes into the fuel distributor line. The fuel chamber of the damper element communicates via a further feed pipe with the fuel distributor line. The feed pipe and the flow tube are axially spaced apart from one another by a distance (A).

  • Patent number: 4676648
    Abstract: A method and an apparatus for determination of run-out of a rotating body, especially an automobile tire, without the need for mechanically contacting the rotating body. The apparatus includes a device for rotating the body, a scanning system with a transmitter for transmitting parallel rays directed toward the rotating body, a receiver to receive the residual rays not blocked by the rotating body, and an analyzer circuit for determination of variations in blockage on the basis of which run-out of the rotating body is determined.

  • Patent number: 4615320
    Abstract: A damper element is proposed which serves to damp a pulsating fluid flow, and in particular to smooth out and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damper element includes at least one damper diaphragm which is fastened in a damper housing and defines a fluid chamber on one side. A connection fitting is disposed on the damper housing and is inserted into a plug connection of a fluid flow cross section. A flow opening is embodied in the fluid flow cross section, being open toward the fluid chamber and toward the fluid flow cross section. The flow opening and the fluid flow cross section are penetrated by a flow tube arranged to protrude therethrough, and into which a first fluid line, which discharges into the fluid chamber, is embodied. Between the flow tube and the wall of the flow opening, an annular, second fluid line is embodied.

  • Patent number: 4409904
    Abstract: A double-axle drive for trucks of a railway vehicle has a drive motor with a drive shaft extending parallel to the longitudinal axis of the vehicle and a respective gearing mechanism engaged with each end of the drive shaft. Each gearing mechanism is drivingly coupled to a hollow shaft which concentrically surrounds a respective wheel-set axle. The wheel-set axle and hollw shaft are coupled by elastic couplings provided at each end of the hollow shaft. Each elastic coupling includes a coupling half mounted on the hollow shaft and a coupling half axially aligned therewith mounted on the axle. One coupling half has a plurality of radially extending pins and the other has a plurality of radially extending arms, the pins and arms being positioned alternately in a rotational direction. Elastically yieldable elements are provided between the pins and arms, are initially tensioned, and engage surfaces on the pins and arms which are not parallel to the wheel-set axle.

  • Patent number: 4172643
    Abstract: The invention relates to an apparatus for internal measurement of the exposure in photographic cameras where the light penetrating the picture-taking or objective lens is fed by way of a mirror to a photoelectric cell.A marginal reflective surface faces the objective lens and surrounds a picture window adjacent the film surface. The marginal surface is formed as a concave mirror the optical axis of which is inclined to the optical axis of the objective lens so as to reflect part of the light therefrom to the photoelectric cell.

  • Patent number: 4050543
    Abstract: A lubricating device for dispensing a prescribed amount of lubricant onto gearing at intervals during the operation or immediately upon starting the gears. The lubricating device is composed of a tank having a bell-like housing located therein. The lower edge of the bell is spaced upwardly from the bottom wall of the tank to permit lubricant to flow inside the bell. A valve member is cooperable with the bottom wall of the tank, which bottom wall has openings therein, and is operatively connected to the bell. The valve is opened simultaneous with a closing of the gap between the lower edge of the bell and the upper surface of the bottom wall so that the lubricant within the bell is dispensed out through the discharge openings in the bottom wall of the tank.
