  • Patent number: 4794904
    Abstract: An internal combustion engine is provided with a volume-displacement supercharger. The supercharger has an interior with an inlet or suction side and an outlet side. An injection nozzle is located within a passage located directly in the supercharger and directs fuel into the supercharger interior at the suction end of the interior.

  • Patent number: 4604040
    Abstract: A displacement machine for a fluid comprising a housing including a spiral wall containing a displacement body including a spiral wall engaged with the spiral wall of the housing to form chambers therewith. The spiral wall of the displacement body extends over an angle greater than 360.degree. to provide overlapping first and second ends and the spiral wall extends axially on both sides of a transverse disc. The center of the displacement body is rotated around a closed circular path, and a crank arm is pivotably connected to the housing at a first pivot axis and to the displacement body at a second pivot axis in the region of the spiral wall of the displacement body. The transverse disc has a radial terminal edge extending between the overlapping first and second ends of the spiral wall of the displacement body.

  • Patent number: 4531899
    Abstract: A positive displacement rotary gas compressor pump comprising a ring piston having an annular wall with a gap forming confronting inlet and outlet ends, the outlet end, during the compression of the gas in the inner and/or outer pumping chambers, cooperating with a bridging wall portion joining two concentric cylinder walls, or with the end of the inner cylinder wall near its transfer port, so that the gas is compressed before being discharged from the pump.

  • Patent number: 4526521
    Abstract: A positive displacement rotary pump based on the spiral principle in which the piston is given a complex orbital motion by a crankshaft drive, the piston being also pivoted to a second guide element, this pivot point reciprocating along an open path. The second guide element is constructed to provide compactness and ease of manufacture.

  • Patent number: 4514153
    Abstract: In a vane pump a hollow cylindrical rotor (7) is mounted for rotation about its axis within a housing (1) and is arranged to be driven by a belt driven pulley (54) mounted on one end (19) of the rotor. Extending eccentrically within the rotor (7) is a shaft (11) which has its opposite ends (10) and (24) fixed in passages (9) and (23) respectively in the end portions (5) and (15) of the housing (1) so that the shaft (11) is not rotatable. The vanes (27) of the pump are rotatably mounted on the shaft (11) so that they extend axially of the shaft and project radially through axially extending openings in the cylindrical wall of the rotor (7). The vanes (27) are thereby rotated on the shaft (11) when the rotor is driven, and the portions of the vanes projecting through the cylindrical wall of the rotor sweep a pump chamber (13) surrounding a portion of the rotor to convey fluid from an inlet to an outlet of the pump.

  • Patent number: 4508089
    Abstract: In a method of regulating the delivery of the combustion fluid (i.e. air or mixture of air and fuel) to an internal combustion engine (1), the combustion fluid is conducted through a gas engine or positive displacement device capable of operating as a fluid motor or a fluid compressor (2) which is drivingly coupled with the internal combustion engine, and the flow rate through the device (2) is varied in the sense of the desired load change by means of a control device (3, 23) on the device. The positive displacement device (2) may be operated as a fluid motor and/or as a supercharger. As a fluid motor the work done by the expansion of the combustion gas is used to assist the engine (1), whereas the engine (1) drives the gas engine (2) when operating as a supercharger. In a preferred embodiment the device (2) is of the rotary vane type (FIG.

  • Patent number: 4483428
    Abstract: In a coupling for a drive device, such as an internal combustion engine, a rotor and an entraining disc are connected. The entraining disc is movable relative to a drive disc so that it can be selectively coupled with the drive disc. A housing at least partly encloses the drive disc and supports a pressure chamber adjacent the entraining disc. The pressure chamber includes a movable cover interconnected with the entraining disc. By regulating the pressure within the chamber, the entraining disc can be coupled or decoupled relative to the drive disc. When coupled to the drive disc, the entraining disc drives the rotor.

  • Patent number: 4463554
    Abstract: In an internal combustion engine a rotary gas motor, driven by the intake gas of the engine, drives pump providing secondary air to the engine exhaust at low engine load, and at high load a clutch connects the pump and the motor to the engine shaft, the output of the pump and the motor being delivered to the engine intake.

  • Patent number: 4455987
    Abstract: A method and an arrangement for controlling exhaust return quantities of an automatic-ignition, internal combustion engine comprising a camshaft-driven piston injection pump and an exhaust control element in an exhaust return pipe. Pressure pulses occurring in an output pressure line of the injection pump during the injection-active delivery stroke are directly or indirectly detected as regards their pulse duration as the injection duration T.sub.E and their pulse intervals as the injection period T.sub.P. A certain injection stroke or a certain quantity of fuel to be injected per work cycle may be assigned, pump-specific, to each pair of values of these quantities through a known pump stroke curve. To control the return quantity of exhaust in dependence upon the quantity of fuel injected, the dependence between the pairs of values of T.sub.E, T.sub.P on the one hand, and control quantities for the return quantities of exhaust on the other hand, are stored in an at least two-dimensional identification field.

  • Patent number: 4417857
    Abstract: A piston pump, for use for example for operating auxiliary mechanisms in motor vehicles, has a piston 1 which is reciprocated in a cylinder 2 by an eccentric 20 and a return spring 18. The cylinder 2 has an outlet valve 23, and inlet openings 4 in its side wall. Instead of moving the piston 1 so far downwards in the suction stroke of the pump that the piston head 6 L is below the inlet openings 4 to allow fluid to flow into the pump chamber 10, the piston is provided with a peripheral groove 13 and openings 11 in its side wall. The openings 11 lead to a recess 17 in the piston head and hence to the pump chamber 10. The groove 13 moves into communication with the inlet openings 4 at two separate times in each to and fro movement of the piston, that is in each pumping cycle, so that the fluid being pumped can only flow into the pump chamber from the inlet openings 4 during these two times.
