摘要： A reciprocating cutter incorporating at least one saw blade and being optionally provided with a cooperating guard. The guard provides a protective cover for the blade or blades of the cutter and, through a spring-loaded biasing thereof, cooperates with the cutter to both stabilize the blade or blades and the workpiece and provide a degree of control for the movement of the cutter through the workpiece. The cutter, which may utilize a single reciprocating blade with which a spring-biased guard cooperates, in most instances will comprise a pair of alternately reciprocating blades, the teeth of which are selectively set to define a single clean kerf in the workpiece. The blade or blades can comprise the sole cutting device in a hand-held motor-driven implement, or alternatively can constitute an attachment, either permanent or removable, for a hand-held motor-driven hedge trimmer incorporating reciprocating trimmer blades to which the saw blades will be operably joined for simultaneous reciprocation therewith.

摘要： A user-replaceable pumping chamber for a consumer piston pump has a reciprocating piston seal secured to the end of a piston by a threaded fastener. The chamber further has a smooth-bored cylindrical sleeve surrounding the seal to form a cylindrical wall for the chamber. The seal is retained to the piston by a threaded shoulder screw and washer acting against an O-ring in an end face of the seal. The housing has an aperture providing access to the cylindrical sleeve to permit levering a worn sleeve out of the housing.

摘要： A diaphragm pump for pumping a fluid, such as paint, includes a diaphragm separating a first chamber for accommodating and dispensing the paint from a second chamber for accommodating a drive fluid, and a piston that reciprocates to drive the drive fluid within the second chamber in order to flex the diaphragm to provide the pumping action within the first chamber. The diaphragm pump also includes a backing ring mounted adjacent the diaphragm that is configured to distribute the drive fluid across the diaphragm to cause a flexible region of the diaphragm to flex toward the first chamber from the outer perimeter inward toward a central pumping surface in a rolling manner. This diaphragm movement results in substantially all of the paint adjacent the diaphragm within the first chamber to move out of the first chamber when the diaphragm reaches its travel limit, and thus improves the efficiency of the diaphragm pump. Additionally, the diaphragm pump includes a drive fluid inlet formed within the piston, such that reciprocating movement of the piston results in an inflow of drive fluid into the second chamber. An input port in the piston is continuously submerged in the drive fluid when open, thereby substantially eliminating the introduction of air into the drive fluid system and thus reducing drive fluid priming problems.
摘要翻译： 用于泵送诸如油漆的流体的隔膜泵包括隔膜，其分隔用于容纳和分配涂料的第一室，用于容纳驱动流体的第二室;以及活塞，其往复运动以驱动第二室内的驱动流体 以便使隔膜弯曲以在第一室内提供泵送作用。 隔膜泵还包括邻近隔膜安装的背衬环，其被构造成将驱动流体分布在隔膜上，以使得隔膜的柔性区域在滚动中从外周向内朝向中央泵送表面向第一腔室弯曲 方式。 当隔膜达到其行程极限时，该隔膜移动导致邻近第一室内隔膜的所有涂料基本上移出第一室，从而提高隔膜泵的效率。 此外，隔膜泵包括形成在活塞内的驱动流体入口，使得活塞的往复运动导致驱动流体流入第二室。 当打开时，活塞中的输入端口连续地浸没在驱动流体中，从而基本上消除了将空气引入到驱动流体系统中，从而减少驱动流体引发问题。

摘要： A pressure relief assembly for use with a paint pump having a chamber with a pressure relief port located immediately adjacent an inlet port of the pump. The pressure relief assembly includes a mounting member, inlet washer, rupture pad and outlet washer. The mounting member is threaded on its exterior surface and includes an inlet end, an outlet end, and a relief passage extending between the inlet and outlet ends. A rupture recess in the inlet end is sized to receive the inlet washer, rupture pad and outlet washer, with the rupture pad positioned between the washers. The inner diameter surface of the outlet washer is convex. The pressure relief assembly is screwed into the pump with the inlet end adjacent to the pressure relief port. The rupture pad forms a seal between the pump chamber and atmosphere that ruptures to vent the chamber when the pressure within the chamber exceeds a predetermined rupture pressure.
