    Abstract: There is described a system and method for filling an engine fuel manifold. An adaptive filling function is used to determine a flow rate at which fuel is to be delivered to the fuel manifold. The filling function receives as an input a present measurement of the engine's speed and computes the flow rate accordingly. The fuel manifold may then be filled according to the computed flow rate so as to match the engine's speed. Appropriate fuel/air ration conditions can therefore be achieved for successful engine start.

    Abstract: Disclosed valves for drinking from a portable fluid container allow for manual actuation of the valve between an open configuration that permits fluid flow and a closed configuration that substantially prevents fluid flow. Disclosed valves comprise a valve housing having inner bore fluidly coupled to an inflow channel and an outflow channel that are angled with respect to one another, and a reciprocating valve member that is adjustably positioned partially within the bore to open and close the fluid flow pathway through the bore from the inflow channel to the outflow channel. The reciprocating valve member is shaped such that it can prevent fluid flow when fully inserted within the bore to a closed configuration, and can allow fluid flow when the valve member is retracted from this closed position by a relatively short distance to an open configuration.

  • Patent number: 8887756
    Abstract: A backflow prevention device including an upstream shutoff valve configured to allow a user to control the water flow stream through the housing. The upstream shutoff valve includes an obstruction. The obstruction is configured to prevent water flow at a first position and allow water flow at a second position. The obstruction is also configured to rotate about an axis of rotation between the first position and the second position. The upstream shutoff valve also includes a seal. The seal is configured to sealingly engage a sealing surface in the housing at the first position. All points of engagement between the obstruction seal and the sealing surface are located downstream of the axis of rotation of the obstruction.

  • Patent number: 8875733
    Abstract: A check valve module. The check valve module includes an orifice, where the orifice is configured to allow the water flow stream through the check valve module. The check valve module also includes a clapper. The clapper is configured to allow the water flow stream through the orifice when open and prevent the water flow stream through the orifice when in a closed position by mating with the orifice. The check valve module further includes a fulcrum apparatus about which the clapper is allowed to rotate, a rotational constraint apparatus which directs the rotation of the clapper and a lateral constraint apparatus which directs the motion of the fulcrum toward and away from the orifice.

  • Publication number: 20140308106
    Abstract: A void protection system for a mining shovel having an operator input device includes an independent metering valve assembly including one or more fluid source-cylinder valves for fluidly connecting the fluid source to the hydraulic cylinder. The system also includes a sensor assembly for monitoring the fluid pressure within the rod end and the head end of the hydraulic cylinder, and a control module. The control module is configured to monitor movement of the operator input device, monitor pressure within the hydraulic cylinder, increase the opening of the corresponding fluid source-cylinder valve and increase fluid flow from the fluid source to fill corresponding end of the hydraulic cylinder until pressure in the corresponding end of the hydraulic cylinder is above a first threshold pressure.

  • Publication number: 20140299209
    Abstract: Disclosed therein is a gas valve having automatically blocking means, which is mounted at an inlet side of a valve body having a ball valve so that the gas valve does not need additional blocking means for blocking a gas pipe at the time of a gas leak, and which returns a blocking member to its original position when the valve is opened after coping with the gas leak at the leaked portion, thereby making maintenance easy.

  • Patent number: 8839816
    Abstract: The control mechanism (18) for a pressurized-gas oral cleaning appliance (10) includes a hollow valve member (44) for receiving gas from a pressurized source thereof (14) and for delivering gas to a gas exit assembly. A gas releasing assembly includes a user-activated actuation member (26) and a pusher member (36), wherein movement of the actuation member moves the pusher member and the valve member in a forward direction to a first position where gas enters the hollow interior of the valve. Further forward movement of the actuation member results in the valve member aligning with the pusher member in such a relationship that the valve member moves rearwardly by action of a spring (67) to a second position where the gas in the valve member exits through the openings and the groove to a gas exit line (68).
