  • Publication number: 20110073191
    Abstract: A hydraulic manifold has features adapted to the needs of hybrid vehicle applications. In one embodiment, multifunction valves selectively regulate fluid flow among primary and auxiliary flow paths. A normally closed butterfly valve is biased by a relatively small secondary biasing force against rotation in first and second (opposite) directions, and by a relatively large principal biasing force against rotation in the first direction past a transitional angular position at which the principal biasing force takes effect. An actuator selectively controls the transitional angular position and the magnitude of the principal biasing force. In the first direction, flow must overcome only the secondary biasing force to pass the valve. In the second direction, any flow sufficient to overcome the secondary biasing force but not the principal biasing force will divide into a first flow passing the valve and a second flow induced to enter an auxiliary path upstream.

    Abstract: A valve assembly having a body, a valve, a contact surface of the valve, and a gap surface of the valve. The body has an interior surface that defines a flow passage. The valve is positioned in the body. The valve is positioned at an angle with respect to the interior surface of the body when the valve is in a closed position in order to prevent the valve from sticking to the body. The contact surface contacts the interior surface of the body when the valve is in a closed position. The gap surface is spaced apart from the interior surface when the valve is in the closed position.

  • Publication number: 20100206264
    Abstract: Throttle valves often have the problem that the throttle must be precisely positioned with and fixed to the throttle shaft. In the throttle valve (2) proposed by the invention, hardening filler material (10) is inserted into the intermediate space (22) between the throttle (6) and the throttle shaft (8). After said filler material (10) has hardened, the throttle (6) is precisely positioned relative to the throttle shaft (8) and fixed in a torque-proof manner. The throttle valve may be used for controlling the output of an internal combustion engine.

  • Patent number: 7765981
    Abstract: An exhaust brake has a body with a passageway for exhaust gases therein. A valve member is movably located within the passageway for selective movement between an open position where the valve member opens the passageway and exhaust gases are free to move through the passageway and a closed position where the valve member blocks the passageway and the passage of exhaust gases through the passageway. The valve member has an aperture therethrough to permit a limited flow of exhaust gases through the aperture when the aperture is open. An exhaust valve actuator mechanism is coupled to the valve member for moving the valve member between the open position and the closed position. A closure member is positioned adjacent to the aperture.

    Abstract: A drain valve used on an at least partially dielectric container has a valve housing made of electrically nonconductive plastic, fixed to the container, and forming a passage opening into the container so that fluent contents of the container can flow out of the container through the passage. A valve body formed at least partially of an electrically conductive material is movable in the passage between a closed position blocking flow through the passage and an open position permitting flow through the passage. An actuating element outside the housing is connected to the body for shifting same between its positions.

  • Patent number: 7758017
    Abstract: Various exemplary embodiments of a butterfly-type valve that provide a reduction in the unseating torque are disclosed that include a valve body defining a flow passage therein, and a closure disc disposed in the flow passage that has an axis of rotation about which the closure disc rotates between open and closed positions. The valve includes a cylindrical body liner disposed within the valve, which includes a circumferential sealing surface that is engaged by the closure disc to establish a seal when the closure disc is rotated to a closed position. At least one resilient band is at least partially interposed between the valve body and the cylindrical body liner, and at least a portion of the resilient band is tapered to a reduced thickness. The taper reduces the forces associated with the engagement by the closure disc, to thereby reduce the unseating torque required to open the closure disc.

  • Patent number: RE42940
    Abstract: A throttle control apparatus for an engine on a vehicle is provided, in which the number of component parts in the position detection means and the driven means is reduced to improve the accuracy in its position control and at the same time an integrated wiring is achieved and connectors are aggregated. The position detection means for detecting the position of a control valve, the driven means for controlling the position of the control valve, the means for processing control signals, an output from the position control means for controlling the position of the control valve are disposed within a sealed space defined by a body supporting a control valve shaft, and a cover. Based on the fact that the number of component parts of the position detection means may be reduced, the mechanical hysteresis and electrical hysteresis may also be reduced to improve the accuracy in controlling the control valve position, and it is possible to aggregate the connectors.
