摘要： A two-stage air-hydraulic booster having two pumping chambers, with one being a relatively large-volume, low-pressure chamber and the other a relatively small-volume, high-pressure chamber and with both chambers being formed, in part, by pumping structure carried by an air-operated piston. The ratio of the area of the air-operated piston to the area of the hydraulic cylinder for the large-volume, low-pressure chamber is relatively low whereby a large volume of fluid per inch of stroke is delivered to the system while the ratio of the area of the airoperated piston to the area of the high-pressure, small-volume chamber is high to deliver a small volume of fluid per inch of stroke of the air-operated piston. The structure provides for minimal consumption of operating air in both advancing the movable air-operated piston in a pumping stroke and in return of the air-operated piston to an initial position.
摘要翻译：一种具有两个泵室的两级气动增压器，一个是相当大体积的低压室，另一个是相当小体积的高压室，并且两个室部分地由泵送结构由气动活塞承载。气动活塞的面积与用于大容量低压室的液压缸面积的比例相对较低，由此每英寸行程的大量流体被输送到系统，而比例气动活塞到高压，小容积室的区域的面积高，以便每英寸行程的气动活塞输送少量流体。该结构提供了在泵送冲程中使可移动气动活塞前进并且将气动活塞返回到初始位置的操作空气的最小消耗。

摘要： An adaptor plate for use in removal and installation of ball joints from a knuckle and a tool kit including the same. The plate includes elongated, arcuate slots arcuately arranged in the form of a circle for adjustable receipt of threaded studs on a knuckle so that the plate may be secured to the knuckle. The plate is further provided with a pair of oppositely located slots so that when the plate is secured to the knuckle, one of the slots will be adjacent one ball joint on the knuckle and the other slot will be adjacent the other ball joint. As a result, the slots may receive the jaws of a pulling tool for both ball joint removal and insertion operations without requiring reorientation of the plate on a knuckle between the two operations. The tool kit includes the foregoing adaptor plate along with a puller and a threaded pressure applying member which may alternately receive a first head for driving ball joints from the knuckle, a second head having a cavity for pushing ball joints into the knuckle and an aligning nut for use in either of the operations.
摘要翻译：用于从转向节移除和安装球窝接头的适配板以及包括该转接节的工具包。该板包括以圆形形式圆弧形地布置的细长弧形槽，用于可调节地接收转向节上的螺柱，使得板可以固定到转向节。该板还设置有一对相对设置的槽，使得当板被固定到转向节时，其中一个槽将与转向节上的一个球窝接头相邻，另一个槽将与另一个球窝接头相邻。结果，槽可以接收用于两个球窝接头移除和插入操作的牵引工具的钳口，而不需要在两个操作之间的转向节上重新定位板。工具套件包括上述适配器板以及拉拔器和螺纹压力施加构件，其可以交替地接收用于从转向节驱动球窝接头的第一头部，具有用于将球窝接头推入转向节的空腔的第二头部和对准螺母用于任一操作。

摘要： A manually operable high pressure release valve in a high fluid pressure system such as an air operated hydraulic pump. The release valve includes a manually operable pilot poppet valve disposed within a larger, manually operable poppet valve, the two poppet valves having a single manual actuator. Release of high pressure is allowed with a minimum of manual effort by first bleeding off a portion of the fluid under high pressure through opening of the pilot poppet valve until the pressure is reduced to a level whereat the larger poppet valve will easily open.

摘要： A tool for assembly and disassembly of a limited slip differential including a step plate engageable against one side gear of the differential, an internally-threaded member engageable against the other side gear of the differential, a forcing screw threadable into the threaded member and engageable with the step plate whereby rotation of the forcing screw forces increased separation of the side gears relative to each other by compressing of a Belleville spring between each side gear and the differential case to free the pinion mate gears for inward movement to remove washers associated therewith, and a handle member connected to the internally-threaded member extendable outwardly of the differential case and provided with a pawl engageable with a tooth on a side gear to result in rotation of the engaged side gear and a pair of pinion mate gears of the differential to cause the latter to walk on the other side gear until the pinion mate gears are positioned for removal through openings in the differential case, with the rotation of the handle being about an axis defined by the forcing screw, together with a method of disassembling a limited slip differential by use of a tool as described above.
