摘要： An improved splined cam phaser includes four assemblies: a sprocket assembly, an inner hub assembly, a cover assembly, and a piston assembly. The joined assemblies provide phaser function at reduced manufacturing cost. The component parts of the assemblies are re-configured from analogous parts in the prior art cam phaser to permit much of the improved phaser to be manufactured inexpensively by powdered metal forming or by stamping or drawing from sheet metal, in contrast with the prior art phaser wherein all parts are formed expensively either by machining from forged blanks or by investment casting. These changes reduce not only the cost of manufacture but also reduce the weight and axial length of the phaser, an important customer acceptance criterion, and improve the speed of response. Further, the proportions of some parts are altered such that all radial and axial loads are borne by a single large bearing in place of two small sequential bearings in the prior art phaser, thus reducing variability in axial alignment of the component parts.

摘要： A wiper seal for preventing leakage of oil between advance and retard chambers formed between rotor vanes and stator lobes in a vane-type camshaft phaser is a monolithic structure made from a single material that includes a wiper element and a compressible spring element extending from the wiper element. The spring element is designed as a cantilevered arm and provides a sealing pressure to the wiper element. The wiper seal may further include a rib element as part of the monolithic structure that vertically extends the wiper element towards the spring element. The rib element assists in preventing over-compression of the cantilevered arm and in preventing tangling of a plurality of wiper seals during handling and shipping. The wiper seal is provided at the tip of each rotor vane and/or stator lobe of a vane-type camshaft phaser for varying the timing of combustion valves in an internal combustion engine.

摘要： An improved releasable and reusable self-sealing plug for mechanically sealing a bore. A cylindrical body is formed on its outer surface to retain radial sealing means such as an O-ring. An oversize annular cap at the outer end of the body limits ingress of the plug into a bore, and a pair of opposed, flexible limbs terminating in flanges beyond the inner end of the body are compressed radially during insertion of the plug and spring out at completion of insertion to grip the inner entrance to the bore, thus holding the O-ring and plug in the bore. Insertion may be accomplished manually without the aid of tools. The plug cannot be driven out by pressure on the bore, but is easily removed by recompression of the limbs and flanges and withdrawal of the plug by, for example, needle-nose pliers. The plug may be formed inexpensively and easily by injection molding of a suitable plastic polymer.
摘要翻译：一种改进的可释放和可重复使用的自密封塞，用于机械密封孔。在其外表面上形成圆柱体以保持诸如O形环的径向密封装置。在主体外端的尺寸较大的环形帽限制了塞子进入孔的入口，并且一对相对的，柔性的四肢终止于主体的内端之外的凸缘，在插入插头期间被径向地压缩并弹出完成插入以夹紧孔的内部入口，从而保持O形环并将其插入孔中。插入可以手动完成，而无需工具的帮助。插头不能通过孔上的压力驱动，但是可以通过肢体和法兰的再压缩以及例如针嘴钳取出插头而容易地移除。插塞可以通过注塑成型合适的塑料聚合物而廉价且容易地形成。

摘要： Installation/removal assembly and method are disclosed that reduce forces required for installing and removing from a wellbore hydraulic artificial lift installations, such as, for example, hydraulic reciprocating pumps, hydraulic jet pumps, coil tubing hydraulic jet pumps, and other hydraulically operated installations. The installation/removal assembly is provided with a hydraulically activated latch and spear assembly that, in a preferred embodiment, includes no radially extending latch elements for securing a bottomhole assembly to a reservoir connection, such as a seating nipple designed for use with mechanical latches. A bottomhole assembly is provided with relatively moveable inner and outer members that move between closed and open positions for respectively sealing or equalizing, differential pressure across a one-way valve that arises when the pump is turned off. The pressure above the one-way valve may be the same as the annulus pressure between the production tubing and the bottomhole assembly of the hydraulic artificial lift installation. External communication embodiments of the present invention communicate directly to the annulus between the production tubing and the bottomhole assembly of the artificial hydraulic lift installation. Internal communication embodiments of the present invention communicate internally of the outer member through the pump output port to the annulus to avoid debris that may exist in the annulus below a pump discharge port.
摘要翻译：公开了安装/拆卸组件和方法，其减少了从井筒液压人造举升装置（例如液压往复泵，液压喷射泵，盘管液压喷射泵和其它液压操作装置）的安装和拆卸所需的力。安装/拆卸组件设置有液压致动的闩锁和矛形组件，在优选实施例中，该组件不包括用于将井底组件固定到储存器连接件的径向延伸的闩锁元件，例如设计用于机械闩锁的座椅接头。井底组件设置有相对可移动的内部和外部构件，其在关闭位置和打开位置之间移动，以分别在泵关闭时产生的单向阀上的压差或均衡压差。单向阀上方的压力可以与生产管道和液压人造举升装置的井底组件之间的环形压力相同。本发明的外部通信实施例直接与生产管道和人造液压升降机装置的井下组件之间的环路通信。本发明的内部通信实施例通过泵输出端口将外部构件内部通信到环形空间，以避免可能存在于泵排出口下方的环形空间中的碎屑。

摘要： A hydraulic manifold assembly for variable actuation of engine valves. First and second plates have portions of flow passages integrally molded therein. The plates are formed preferably by injection molding of a suitable polymer, for example, glass-filled PPA, and are joined together as by cementing or preferably by fusion welding along mating surfaces to form the full pattern of flow passages. The assembly further comprises a retainer for retaining a plurality of individual solenoid-actuated valves in sockets formed in the plates. The retainer is similarly formed preferably by injection molding of a suitable polymer and is formed to function simultaneously as a positive crankcase ventilation (PCV) baffle.
