摘要： In a method for operating a fuel system of an internal combustion engine, the fuel system has a fuel tank and a ventilation device, which has at least one vent valve, for ventilating the fuel tank. The magnitude of deformation caused by an internal pressure of the fuel tank of a deformation zone of the fuel tank is ascertained and the vent valve is opened when the magnitude of deformation exceeds a limit value.

摘要： Prior art fuel line check valves remain closed after engine off and cool down. Diurnal heating and the resultant pressure increase in the fuel line causes fuel vapor emissions through small openings in the fuel line (e.g., at the injector tips). The invention provides a check valve for a vehicle fuel line which opens in response to engine cooling and remains open while the engine is off to relieve subsequent increasing pressure in the fuel line due to diurnal heating thereof.

摘要： 1,043,806. Valves. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO. March 20, 1964 [March 26, 1963], No. 11963/64. Heading F2V. [Also in Division G3] A valve suitable for insertion in the line between a compressor and a receiver comprises an inlet chamber 12, a delivery chamber 14 and a check valve 60 allowing flow from the inlet to the delivery chamber. The check valve forms part of a piston 46 slidable in bore 47 and co-operating with a stop 48 carried by a spindle 42. The latter also carries an exhaust valve 36 loaded by a spring 54. When the pressure in the inlet chamber reaches a predetermined value it unseats the exhaust valve with a snap-action and the lowered pressure in the inlet chamber then allows the piston 60 to be driven downwardly by the receiver pressure until it engages stop 48, whereby the exhaust valve is retained open until the receiver pressure drops to a second, lower, predetermined value. In modifications, the piston and exhaust valve are rigidly interconnected, or the spindle 42 is rigid with the piston and the exhaust valve is slidable on the spindle with its loading spring in exhaust chamber 35. A filter may be provided in the inlet chamber upstream of the check valve. The latter comprises an annular gasket supported on a plate 64 retained by a snap-ring 66.

摘要：一种四功能防水锤空气阀组，包括负压吸气阀(1)、微量排气阀(2)和高速排气阀(3)及控制隔离阀(4)，高速排气阀(3)通过控制阀连接在负压吸气阀(1)的顶部；二者分开设置而非相互共用，一方面为独立选型，分别满足高速排气和高速吸气二个不同的流量或速度或口径要求，另一方面为叠加吸气，在负压时都吸气相互补充，三个孔口的独立性允许高速吸气孔口与微量排气孔口组合成"注气微排阀"或"高吸微排阀"，从而使本阀组具有抑制空腔弥合水锤的功能。该四功能防水锤空气阀组包括三个孔口相互独立的功能、由高速排气孔口设置控制隔离阀提供的可以被人为切断复又可以开启的功能、由后两个功能组合形成特殊功效的功能以及高速排气孔口可以大幅缩小的功能。
