摘要： A fully-integrated, flow-control module for top-fill fuel tanks is designed to operate with a fuel line attached that supplies fuel under constant pressure. A main flow control valve within the flow-control module closes automatically when the fuel tank is full, and automatically opens when the fuel level drops a certain amount below the full level. A spring-biased valve plunger of the main flow control valve has a bleed aperture that diverts a small amount of incoming fuel to a bleed path that is controlled by a fuel level float that operates on a lever arm that either opens or closes the bleed path. When closed, fuel pressure beneath the valve plunger increases sufficiently that the plunger biasing spring is able to exert a force sufficient to close the valve plunger. Bleed path control hysteresis prevents rapid cycling of the main flow control valve.

摘要： A device for actuating valves and determines an actuation duration for a valve of a target system from a specified actuation duration for a valve of a reference system with which a required pressure change can be achieved in the reference system in order to achieve the required pressure change in the target system. The device ascertains the effective valve opening time belonging to the specified actuation duration for the valve of the reference system, calculates the effective opening time of the valve of the target system from the effective opening time said opening time of the valve of the target system being used to achieve the same pressure change in the target system as in the reference system, and then determines a valve actuation duration required to achieve the effective opening time of the valve of the target system.

摘要： Disclosed is a leak-proof device for a water inlet valve. A control valve is installed in a valve body for opening and closing a water inlet channel and a water outlet channel. An outer water tank and a leak-proof water tank are installed on the valve body. An inner water tank is disposed in the outer water tank, with the height of the inner water tank being lower than that of the outer water tank. The leak-proof water tank is in communication with the inner water tank via a water-passing channel A lever is pivotally connected to the valve body. Two ends of the lever are connected with an outer float and an inner float. The inner float is provided with a plug that is movable to block the water-passing channel. The leak-proof float is connected to the control valve.

摘要： A fully-integrated, flow-control module for top-fill fuel tanks operates with a fuel line attached that supplies fuel under pulsating pressure. There are two bleed paths in the module, which open and close sequentially in response to the position of a fuel float within the module. In order for a main valve plunger, which controls fuel entry into the tank, to fully close, both bleed paths must be closed. A first bleed path closes first, followed by closure of the second. For the main valve plunger to fully open, both bleed paths must be open. The second bleed path opens first. Movement of the main valve plunger is controlled by both a biasing spring and pressure beneath the plunger. Pressure beneath the plunger builds up to a level sufficient for the biasing spring to fully close the plunger against a valve seat when both bleed paths are closed.

摘要： A fill valve for a water storage tank, the fill valve comprising a riser assembly, a valve housing mounted on an upper end of the riser assembly, a pilot orifice in the valve housing, and a sensor adapted to be mounted within the water storage tank. The sensor is responsive to a water level within the water storage tank, and a pilot valve mechanism opens and closes the pilot orifice in response to the sensor determining the water level in the fill tank.

摘要： A buoyant float including a body having an interior defined in part by a side wall and a bottom extending inward from the side wall. The side wall has an upper edge defining an open top of the body. The float includes a cover sized and shaped for covering the top of the body. The cover attaches to the body to maintain the cover in position relative to the body to cover the open top. The cover has a tubular skirt extending downward and around the upper edge of the body side wall when the cover is in position covering the top of the body. An air pocket is created at an interface between the cover and the body when the float is positioned in liquid to isolate the interface from the liquid and prevent liquid from entering the hollow interior of the body through the interface.

摘要： An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.
