摘要： Pump piston seizures caused by excessive side loads produced by the uneven loading of a large piston return spring are prevented by separating the tappet return function from the piston return function, thereby minimizing the spring force acting on the piston. Preferably, a stronger, heavier load outer spring is mounted between the pump body and the tappet, such that it imparts no load and therefore no side loads to the pumping piston. A weaker, lighter load inner spring imparts less side load to the pumping piston than a conventional piston return spring, because the inner spring need not carry any tappet load. During both the pumping and charging strokes of the piston, the piston return spring can assist the tappet return spring, but the tappet return spring does not assist the piston return spring.
摘要翻译：通过将挺杆返回功能与活塞返回功能分开来防止由大活塞复位弹簧的不均匀载荷产生的过大的侧向载荷引起的泵活塞咬合，从而最小化作用在活塞上的弹簧力。优选地，较重的较重的负载外部弹簧安装在泵体和挺杆之间，使得其不施加负载，因此不向泵送活塞施加侧向载荷。由于内部弹簧不需要携带任何挺杆载荷，内部较弱的内弹簧比常规的活塞复位弹簧赋予泵送活塞少的侧向载荷。在活塞的抽吸和充气冲程期间，活塞复位弹簧可以帮助挺杆复位弹簧，但挺杆复位弹簧不能帮助活塞复位弹簧。

摘要： A fuel pump for an internal combustion engine that transmits fuel with pressure by a lifting movement of a plunger that is caused to lift by a movement of a cam includes a lift amount changing mechanism. The lift amount changing mechanism includes a cam in which a height of a projection is varied along an axial direction of the camshaft, and a cam moving actuator that moves the cam along the axial direction of the camshaft. The lift amount of the plunger is changed by moving the cam along the axial direction of the camshaft. An amount of discharged fuel is controlled by changing the amount of discharged fuel per stroke of the plunger and is not determined only based upon the rotation speed of the engine. Therefore, the amount of discharged fuel can be increased with the engine rotated at a low speed, for example when the engine is being initially started, to improve a starting performance.
摘要翻译：一种用于内燃机的燃料泵，其通过由凸轮的运动引起提升的柱塞的提升运动而传递燃料的燃料泵包括提升量改变机构。提升量改变机构包括突起的高度沿着凸轮轴的轴向变化的凸轮和沿着凸轮轴的轴向移动凸轮的凸轮移动致动器。通过沿着凸轮轴的轴向移动凸轮来改变柱塞的提升量。排出的燃料量通过改变柱塞的每冲程排出的燃料量来控制，并且不仅仅基于发动机的转速来确定。因此，当发动机以低速旋转时，例如当发动机正在起动时，排出的燃料量可以增加，以提高起动性能。

摘要： A piston-type fuel pump has two or more cylinder bores in a barrel. A piston in each cylinder bore has a port for admitting fuel into the cylinder bore. A swash plate assembly includes a wobble plate connected to each of the pistons. The wobble plate is given an oscillatory motion producing reciprocal movement of the pistons. A thin-walled metal bellows defines a closed interior space surrounding the pistons to prevent escape of fuel.

摘要： An electromagnetic pump is disclosed in which a pair of check valves and a pressure-regulating mechanism are inserted in series in a fluid passage extending from a suction inlet to a discharge outlet and a pressure chamber operatively connected with a plunger is provided between the check valves. When a solenoid coil surrounding the plunger is supplied with an intermittent electric current, the plunger moves to and fro, thereby the pressure in the pressure chamber being varied to have the check valves given rise to pumping action. The pressure-regulating mechanism function to control the pressure of fluid discharged from the outlet, thereby absorbing the pulsation generated by the reciprocal pumping action of the plunger.

A contactless displacement type fuel pump for LPG vehicle comprises a pump body(200) in which an inlet(210) and an outlet(220) are formed, a piston(300) installed on the pump body, a linear motor(400) reciprocating the piston, and a linear flexion bearing(100) arranged on both sides of the linear motor. The linear motor strongly supports the piston rod in the radial direction so that the piston reciprocating in the pump body is fixed at the specific position.
