摘要： A float valve mechanism comprising a housing (13) defining a closed chamber (14) having an inlet port (12) and an outlet port (22). The chamber (14) is closed by a cap (17) threaded on to it. The valve head (32) has a conical surface (34) engaging a conical valve seat (23) and a skirt portion (35) having a slightly smaller diameter than the outlet port (22) so that water flowing through the outlet is throttled as the valve nears its closed position. The valve head (32) can be formed separately, of rubber like material, and snap fitted on the valve stem (29).

摘要： A shut-off valve (105; 205; 405; 505) includes a float (106; 206; 306; 406; 506) and a negative G control component (108; 208; 308; 408; 508). The float is configured to occlude a tank outlet (114; 214; 314; 414; 514) at a first fluid level and 1 G (F G ) and unocclude the tank outlet at a second fluid level and 1 G. The negative G control component is operatively connected to the float to limit fluid, e.g. liquid or gas, communication between the tank outlet and an ejector pump (104; 504) during negative G events. An ecology fuel return system (100; 200; 300; 400; 500) includes a tank (102; 202; 302; 402; 502), an ejector pump (104; 504), a float (106; 206; 306; 406; 506), and a negative G control component (108; 208; 308; 408; 508), as described above. The tank has an inlet (112) and an outlet (114; 214; 314; 414; 514). The inlet is configured to be in fluid communication with components of an engine. The ejector pump is in fluid communication with the tank outlet and is configured to pump fuel from the tank to a fuel pump inlet of an engine.

摘要： Disclosed are a water inlet valve for a toilet and a control method thereof: the water inlet valve structure comprises a valve body (1), a water inlet tube (10), a water-stop device with a rubber water-stop pad (3), a float canister device (13), a lifting lever device (11) and a water outlet tube (14). The water-stop device also comprises a water-stop seat (16), a tray (2), a needle valve (4) and a back pressure chamber. The water-stop seat (16) is disposed in front of the water outlet tube (14), with an opening thereof fitting an end face of the rubber water-stop pad (3). The tray (2) connected to the rubber water-stop pad (3) is located on the side opposite to the water-stop seat (16) with respect to the rubber water-stop pad (3). The needle valve (4) is fastened to the tray (2), and located on the side opposite to the rubber water-stop pad (3) with respect to the tray (2). The back pressure chamber is a chamber with a pressure relief opening (121), and accommodates the tray (2) and needle valve (4); the back pressure chamber has a needle valve hole (51) for encasing the needle valve (4). The water inlet valve for a toilet and control method thereof reduce noise and vibration during operation, and are more user-friendly.
