摘要： Pin bosses (1) are proposed for the piston (2) of an internal combustion engine, having in each case one pin bore (3) which has a zenith-side ovality in the region (15) of the bore centre (7), wherein the zenith-side ovality of the pin bore (3) increases starting from the bore centre (7) radially to the outside and radially to the inside, and the nadir-side ovality increases starting from the bore centre (7) radially to the inside. As a result, the shape of the pin bore (3) is adapted to every load-dependent deformation of the piston pin. As a result of this, in addition, the lubrication of the piston pin is improved in the region of the bore centre (7).

摘要： A pump assembly (10) is disclosed which incorporates a double acting power end (12) to operate opposed single or double acting pumps (84, 102). First and second crossheads (30, 64) are reciprocated along the pumping axis (38) by rotation of the crankshaft (20) within the power end (12). A single acting pump is connected to each of the crossheads so that the pumping stroke of the pumps occur in opposite directions as the crossheads are reciprocated. This provides a constant loading of the power end in compression to most efficiently use the power end while realizing the advantages of using single acting pumps. The crossheads are guided for motion along the pumping axis by adjustable cradles (40, 46, 70, 72) which are initially secured to the frame of the pump assembly for limited motion and the crossheads reciprocated through their range of motion to align the cradles with the crossheads and subsequently rigidly secure the frame in the aligned positions as by fastening assemblies (52).
摘要翻译：公开了一种泵组件（10），其包括用于操作相对的单作用或双作用泵（84,102）的双作用动力端（12）。第一和第二十字头（30,64）通过曲柄轴（20）在动力端（12）内的旋转沿着泵送轴线（38）往复运动。单作用泵连接到每个十字头，使得泵的泵送冲程在十字头往复运动时沿相反的方向发生。这提供了压缩功率端的恒定负载，以最有效地使用功率端，同时实现使用单作用泵的优点。十字头被引导以沿着泵送轴线运动，可调节的支架（40,46,70,72）首先被固定到泵组件的框架上以进行有限的运动，并且十字头在其运动范围内往复运动以使托架与十字头并随后通过紧固组件（52）将框架刚性地固定在对准位置。

摘要： An improved piston assembly for high-power internal combustion engines such as supercharged diesel engines. The piston includes separate head and skirt portions. An elongated bearing member having an external journal surface is formed across the bottom of the piston head. A wrist pin, which is attached to or integral with a connecting rod, defines a generally tubular shaped bearing member having an internal bearing surface in which the piston head bearing member is journaled to permit rotational movement between the connecting rod and the piston head. The external journal surface on the piston head is supported by the wrist pin along its entire length to prevent any flexing of the wrist pin when high compressive forces are applied to the piston head. The skirt is connected to the wrist pin by thrust bearings which engage an external journal surface on the wrist pin substantially along its entire length to permit rotational movement between the piston head and the piston skirt.

摘要： A machine, such as the compressor, having a housing formed in two sections. One section encloses a working unit while the second section encloses a driving unit for operating the working unit. A connector unit in the second section is operably connected by removable bearing means to the working unit and to the driving unit. The connector unit has pivoted bearings thereon that are slidable on mating removable bearings on the housing. A window is provided in the second section, through which window all of the bearing means in the second section may be removed without disturbing the working unit in its section. The pivoted bearings are of the so called Mitchell type but are of an improved construction. The bearing surfaces thereof have one or more transverse grooves therein that are symetrically arranged with respect to a plane passing through the pivot bore and perpendicular to the bearing's face. This construction tends to prevent digging in of the bearing when moving along the mating bearing.
