    • A diaphragm pump, particularly for use as a fuel pump in an internal combustion engine, comprises upper and lower housing parts separated by a diaphragm which is clamped between them. The upper housing part comprises an intermediate housing and a top cover fixed on top of it. The intermediate housing has a cross wall which extends across the interior of the upper housing part and which, together with a valve plate within the intermediate housing, divides the upper housing part into three separate chambers, a suction chamber to which the pump inlet is connected, a working chamber, and a pressure chamber to which the pump outlet is connected. The working chamber is situated between the valve plate and the diaphragm. A sunken port is press formed or drawn integrally from the cross wall in an eccentric position, the lower lip of this sunken port being sealed to the valve plate around a corresponding aperture in the valve plate. In this way a passageway is formed communicating the chamber above the cross wall, preferably the suction chamber, with the working cyamber. The seal at the lower lip of the sunken port is formed either by a sealing ring or by the lip being directly fixed to the valve plate.

    • An engine fuel pump of the type having a pulsating diaphragm operated in one direction by an engine driven member, such as an oscillating arm driven by an eccentric on the engine cam shaft, and operated in the other direction by a spring which establishes output or pumping pressure to the needle valve of a float-type carburetor, the pump having inlet and outlet valves which operate upon demand of fuel to the carburetor and permits the diaphragm to pulsate accordingly, characterized by a by-pass valve controlled by intake manifold pressure which by-passes a metered flow of fuel from a pumping chamber to the inlet side of the inlet valve to thereby reduce pumping pressure at normal automotive speeds at which pumping pressure is in excess of that required and which results in an abnormally high fuel level in the carburetor, causing excessive consumption of fuel or flooding of the carburetor, the by-pass becoming inoperative at higher than normal speeds to permit the pumping pressure to increase to its normal designed value at such higher speeds and at which the pumping pressure will not cause the malfunctions referred to which occur at the normal automotive speeds.
    • 一种发动机燃油泵，其具有通过发动机驱动构件在一个方向上操作的脉动隔膜，例如由发动机凸轮轴上的偏心轮驱动的摆动臂，并且通过建立输出或泵送的弹簧在另一个方向上操作 对浮子式化油器的针阀的压力，该泵具有入口和出口阀，其根据对化油器的燃料需求进行操作，并允许隔膜相应地脉动，其特征在于由进气歧管压力控制的旁通阀， - 将来自泵送室的计量流动的燃料流从入口阀的入口侧通过，从而在泵送压力超过所需压力的正常汽车速度下降低泵送压力，并且导致化油器中的异常高的燃料液位 ，导致燃料过度消耗或化油器的淹水，旁路在高于正常速度的情况下不工作，以允许泵送压力 以更高的速度将其压缩到其正常的设计值，并且泵送压力不会引起在正常汽车速度下发生的故障。
