Abstract: In a nonreturn valve having a tubular body, which can be installed in a vertical section of an exhaust line, a valve seat, formed within the tubular body, for at least one float, and at least one circumferential groove, which is open in the downstream direction, the intention is to make available a solution by means of which it is possible to provide a nonreturn valve that is simple, advantageous in terms of production engineering and has a particularly high performance, and to do so in a way which is simple in terms of design and is economical. This is achieved by virtue of the fact that the circumferential rim of the at least one float projects radially over the radially inner circumferential wall section and has an axial lip facing upstream, which extends into the circumferential groove in the axial direction when the at least one float is resting on the valve seat.

Abstract: A safety relief fill valve adapted to being an interface for filling and relieving excess pressure from a closed fluid system. An insert shell retains a piston member for movement between fluid input and fluid holding configurations, the piston member being resiliently biased toward fluid holding configuration. When in fluid holding configuration, the piston member sealingly engages an inlet bore of the insert shell. When in fluid input configuration, the piston member allows fluid flow through the inlet bore. A housing receives the insert shell, thereby limiting relative axial movement and forming a cavity between a portion of the housing the insert shell. This cavity provides mechanical guidance and a flow channel for an overpressure relief system having fluid retaining and fluid relief configurations, the overpressure relief system being elastically biased toward fluid retaining configuration. The elastic bias is overcome responsive to excess pressure within the closed fluid system.

Abstract: A housing has a compression chamber and a first passage, through which the compression chamber communicates with an accumulation chamber. A discharge valve is provided in the first passage and configured to open to supply fuel from the compression chamber to the accumulation chamber in response to increase in pressure in the compression chamber. A second passage is configured to communicate the accumulation chamber with the compression chamber via the discharge valve. A valve element allows fuel flow from the accumulation chamber to the compression chamber. A biasing unit biases the valve element to seat the valve element on a valve seat of the second passage. The sidewall of the valve element and the inner wall defining the second passage therebetween define a throttle midway through the second passage for restricting fuel flow from the accumulation chamber to the compression chamber.

Abstract: A fuel tank valve device equipped with a casing, and a valve mechanism. The valve mechanism has a first valve unit having a first valve connecting hole, and a second valve unit that opens and closes the first valve connecting hole. The first valve unit completely closes the valve flow path by moving by the force in the valve closing direction when the pressure of the second communication path exceeds a preset first pressure value. In a state when the first valve unit is closing the valve flow path, when the pressure of the second communication path exceeds a preset second pressure value that is greater than the first pressure value, the second valve unit receives the pressure from the first valve connecting hole and moves to open the first valve connecting hole, communicating with the valve flow path.

Abstract: A combination neutral valve and check valve assembly is provided for use in connection with a closed hydraulic circuit and a sump such as in a hydrostatic transmission. A cage and check poppet are mounted in a valve body having an opening between the hydraulic circuit and sump. The check poppet is movable between a first position where it closes the valve opening and a second position where it is disengaged from the opening. A check compression spring is mounted in the cage and biases the poppet to the engaged position. A valve shuttle is located in the check poppet and movable between a first position where it closes a check poppet opening and a second position where it is disengaged from the opening. A neutral valve spring is engaged to the valve shuttle and the check poppet to bias the valve shuttle to the disengaged position.

Abstract: A reactive speed hump (2) includes a fluid flow control valve assembly (4). A first valve (18, 20, 21) is naturally open and a second valve (10, 14, 15, 16, 17), naturally closed. Application of fluid pressure on the control valve assembly below a first lower threshold level or above a second higher threshold level allows a flow of fluid from the inlet to the outlet, but an application of fluid pressure on the control valve between said first and second threshold levels allows substantially no fluid to flow between the inlet (7) and the outlet (9).

Abstract: In a fuel vapor processing system, a float valve and a check valve are provided in upper parts of a fuel tank to conduct fuel vapor to a canister via a fuel vapor passage. The check valve includes a low set-pressure valve and high set-pressure valve, and operates in two stages so that the internal pressure of the fuel tank can be favorably controlled by the opening of the low set-pressure valve when the fuel tank is being filled to full so that the sensor associated with the fill nozzle can successfully detect a tank full state, and any excessive rise in the internal pressure of the fuel tank typically caused by a high temperature of the surrounding environment can be avoided by the opening of the high set-pressure valve.
