Abstract: 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. Separate and distinct biasing means perform the respective functions. 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.

Abstract translation: 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。 独立和不同的偏置装置执行各自的功能。 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更少的侧向载荷。 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。

Abstract: A disposable guarded surgical scalpel includes a handle with a blade fixed to it and a slidably mounted guard. The guard can be moved using a single hand. When the scalpel is in use the guard is moved to a retracted position where the blade is exposed; the guard locks in this position to prevent any unintentional movement. When the scalpel is not in use, the guard is moved to an extended position where the blade is covered. When the scalpel has been used on a patient the guard is moved to a disposal position beyond the extended position thus exposing a visual indicia on the handle that indicates that the scalpel should not be reused. The guard also has grooves on the outer surface so as to provide better grip to a surgeon during operation.

Abstract: A miniature scalpel comprising a carrier having a front portion rigidly securing a projecting blade and pivotally securing the back portion of a shield that projects alongside and covers one side of the blade. The front portion of the shield can be pivoted 180 degrees away from the blade into lateral alignment with the back portion of the carrier, thereby forming a handle for the exposed blade. Detent formations can be provided on the carrier and shield, for mating as the handle is formed. The carrier shield can easily be separated from the carrier at the detent, for pivoting back to the closed position.

Abstract: A pump, for supplying high pressure fuel from a fuel tank to an engine via a common rail, includes a motor assembly (20) mounted on top of the fuel tank, a pump assembly (26) positioned within the fuel tank, and a support column (32) rotatably connecting the motor assembly to the pump assembly. A high pressure pump sub-assembly (46) includes a pump body (48) having a drive bore (50) and multiple plunger bores (60) formed therein. The external profile of a drive member (58) which is rotatable within the drive bore engages the radially inner end of pumping plungers (62) disposed in each of the plunger bores for a portion of each revolution to reciprocally move the plungers between radially inner and outer limit positions. Reciprocation towards the inner limit position induces a low pressure in the radially outer end of the plunger bore, thereby drawing fuel via the drive bore without the aid of a low pressure pump.

Abstract: 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.

Abstract: 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.

Abstract: The governor (FIG. 1) includes a second idling spring (supplementary idling spring 42) secured on a force transmission lever (31) acted upon by the main governor spring (34). By means of the second idling spring, the restoring force of a first idling spring (38) on a portion of the idling sleeve path (a) is reinforced in the idling position of an adjusting member (22). This exertion of force on the part of at least the supplementary idling spring (42) is increased in accordance with load by means of a corrective adjusting member (44) when the adjusting member (22) has pivoted into a partial-load position. As a result, in order to improve the starting behavior even in minimum-maximum speed governors, a partial-load rpm located above the idling rpm can be regulated, and a progressively increased supply quantity is controlled at the associated injection pump with increasing load in the lower partial-load range.
