Abstract: A reciprocating compressor drive for driving a pair of opposed horizontally arranged compressor pistons. The pistons are carried by a pair of coaxial horizontal piston rods which are fixed to a crosshead situated between the piston rods and formed with a vertical slot receiving a slide block connected to a crank pin which is driven by a rotary crank drive. A pair of guide bars, which are parallel to the piston rods, extend through upper and lower bores of the crosshead, these bores carrying suitable bearings which slide along the guide bars. A pressurized lubricating system is provided for lubricating components such as the bearings which slide on the guide bars and the crank pin which is received in the slide block, the crosshead preferably being made of a light-weight material such as a plastic and carrying steel guide strips which slidably engage the slide block, the latter as well as the bearings which engage the guide bars preferably being made of bronze while the guide strips which engage the slide block and the guide bars which engage the bearings are preferably made of steel.

Abstract: PURPOSE: To prevent seizure of sliding elements for transmitting the driving force of a swash plate to a piston even if the lubricating conditions are severe, by shaping the flat part of the substantially spherical sliding elements to have a slightly convex curvature.
CONSTITUTION: In a swash plate type compressor shown in the Fig, a flat portion 10b of each spherical sliding element 10 is shaped to have a slightly convex, smoothly curved surface 10c having an extremely large radius of curvature, so that the height H
1 is less than 15μm. Since, with such an arrangement, a wedge-shaped clearance, having an extremely small wedge angle that is decreased gradually in a smooth manner, is formed between the curved surface 10c of the sliding element 10 and the surface of a swash plate 8, lubricating oil attached to the surface of the swash plate 8 is readily drawn into the clearance at the time of high-speed operation, so that a film of lubricating oil for preventing direct contact between them is formed. Further, since the contact point of the swash plate 8 and curved surface 10c is changed for each rotation along with swinging motion of the sliding elements 10 and the amount of lubricating oil circulated is increased resultantly, so that the lubricating conditions can be further improved. Thus, it is enabled to protect the sliding elements 10 against seizure.

Abstract translation: 目的：为了防止滑动元件发生旋转斜盘驱动力传递到活塞，即使润滑条件严重，通过使基本上球形的滑动元件的平坦部分成形为具有略微凸起的曲率。 构成：在图1所示的斜盘式压缩机中，每个球形滑动元件10的平坦部分10b成形为具有非常大的曲率半径的略凸出的平滑曲面10c，使得高度H1较小 超过15mum。 由于通过这种布置，在滑动元件10的弯曲表面10c和斜盘8的表面之间形成楔形间隙，该楔形间隙具有以平滑方式逐渐减小的非常小的楔角，并且润滑 附着在旋转斜盘8的表面上的油容易地在高速运转时被拉入间隙，从而形成用于防止它们之间直接接触的润滑油膜。 此外，由于斜盘8和曲面10c的接触点随着滑动元件10的摆动而随着每个旋转而改变，所以循环的润滑油的量增加，从而可以进一步提高润滑条件。 因此，能够保护滑动元件10免受卡住。

Abstract: An axial multi-piston compressor includes a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the respective cylinder bores, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore concerned, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore concerned, such that a residual part of the compressed fluid is inevitably left in the cylinder bore concerned when the compression stroke is finished. The compressor further includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore concerned into two other cylinder bores disposed adjacent to each other and subjected to the compression stroke.

Abstract: An axial multi-piston type compressor includes: a drive shaft; a cylinder block having cylinder bores surrounding the shaft, a central circular space, and respective radial passages for communicating the bores with the space; pistons slidably received in the respective bores, and a housing associated with the block to define a crank chamber. The pistons are successively reciprocated in the bores by a rotation of the shaft so that a suction stroke and a discharge stroke are alternately executed in each bore. A suction rotary valve is rotationally and slidably received in the space to be cooperated with the passages for successively introducing a fluid into the bores subjected to the suction stroke, through the corresponding passages thereof, and for successively closing the passages of the bores subjected to the compression stroke. A leakage of a compressed fluid occurs at openings of the passages of the bores subjected to the compression stroke, and prevails in a clearance between an outer surface of the valve and an inner surface of the space. The valve includes a circular groove passage formed in the outer surface thereof for recovering the leakage to prevent introduction of the leakage into the crank chamber.
