摘要： An apparatus is provided for equalizing pressure between a lubrication fluid for lubricating a pump and a combustion fluid located at a low pressure side of the pump wherein the pump has a rotatable shaft. The apparatus includes a wall defining a bore within the pump wherein a first end of the bore is configured to receive a lubrication fluid and a second end of the bore is configured to receive combustion fluid. An equalizing element is disposed within the bore for separating the lubrication fluid and the combustion fluid and may be at least partially movable in response to pressure differences caused, e.g., by differences in thermal expansion between the lubrication fluid and the combustion fluid.

摘要： A fuel pump (10) for supplying fuel to an internal combustion engine employs at least one composite pumping plunger (43) disposed within a plunger bore (46) for reciprocation therein. Each composite plunger comprises at least a high-pressure plunger element (48), which is in contact with a high-pressure fuel charge to be delivered by the pump, and an abutting leak-off plunger element (47) disposed between the high-pressure element and a plunger actuating member (50, 52). The plunger elements of each composite plunger are stacked in the direction of reciprocation such that the abutting plunger elements form confronting end faces. The confronting end face of at least one of the elements in each composite plunger is contoured and the confronting end face of the abutting element is non-complementary in shape. This arrangement of confronting faces of abutting plunger elements causes the composite plungers to freely reciprocate within the plunger bores in self-centering fashion and provides a tighter seal at the interfaces of the composite plungers and the plunger bores.

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： An hydraulic head features two or three individual radial pumping pistons and associated pumping chambers, annularly spaced around a cavity in the head where an eccentric drive member with associated outer rolling actuation ring are situated, whereby a rolling interaction is provided between the actuating ring and the inner ends of the pistons for intermittent actuation, and a sliding interaction is provided between the actuation ring and the drive member. The respective inlet and outlet valve trains are also situated in the head, and the head is attachable to an application and/or customer specific mounting plate. The outside diameter of the rolling element is barrel shaped, to compensate for any misalignment of the pistons relative to the drive shaft due, for example, to either tolerance stack up or deflection.
