    • A swash-plate type compressor having a housing, a drive shaft rotatably supported by the housing, a swash-plate slantly secured on the drive shaft, and a plurality of pistons fitted in a cylinder bore formed in correspondence to each of the pistons parallelly to the drive shaft and provided with a pair of concave spherical surface formed therein. Each of the pistons is engaged with the swash-plate via a pair of shoes of substantially semi-spherical shape. The shoe has a convex spherical surface which is in sliding contact with the concave spherical surface of the piston and a flat-side surface which is in sliding contact with the swash-plate. The flat-side surface consists of a chamfered surface annularly formed on the outer portion thereof and a centrally left substantially flat surface with a diameter as large as about 60-90% of that of the whole flat-side surface. The substantially flat surface is formed into an extremely gentle convex surface with a height less than 15 .mu.m at the peak located in the center thereof. The whole surface of the shoe is covered by a solid lubricating film.
    • 具有壳体的旋转斜盘式压缩机,由壳体可旋转地支撑的驱动轴,倾斜地固定在驱动轴上的斜盘,以及安装在与每个活塞相对应地形成的气缸孔中的多个活塞,其平行于 所述驱动轴设置有形成在其中的一对凹球面。 每个活塞通过一对大致半球形的鞋与旋转斜盘接合。 该鞋具有与活塞的凹形球面滑动接触的凸形球面和与斜盘滑动接触的平坦侧表面。 平面由平坦侧表面的外侧部分上形成有圆环状的倒角面和直径大于整个平面侧面的大约60〜90%的中央左侧的大致平坦的面。 在位于其中心的峰处,基本平坦的表面形成为具有小于15μm的高度的非常平缓的凸表面。 鞋的整个表面被固体润滑膜覆盖。

    • A swash plate type compressor for use in air conditioning systems operating with a refrigerant gas in which lubricating oil is previously mixed, comprises a plurality of cylinder bores and pistons, a swash plate chamber wherein a swash plate for reciprocating the pistons within the cylinder bores, is accomodated, a plurality of suction passages communicated with the swash plate chamber, suction chambers and exhaust chambers communicated with the cylinder bores, respectively and at least one sub-suction chamber communicated with the suction chambers through a shaft seal chamber wherein a shaft seal member is accomodated.At least one suction passage which is communicated with the swash plate chamber in the bottom portion thereof is communicated with the sub-suction chamber and the other suction passages are communicated with the suction chambers.The refrigerant gas and liquid oil stayed in the bottom portion of the swash plate chamber is flowed into the shaft seal chamber through the suction passage which is communicated with the bottom portion of the swash plate chamber, and subsuction chamber.The refrigerant gas and liquid oil lubricates and cools the shaft seal member accomodated within the shaft seal chamber and is atomized due to the operation of the shaft seal member.Then, the atomized refrigerant gas is flowed into each of the cylinder bores through the suction chambers.Therefore, the refrigerant gas is uniformly compressed within each of the cylinder bores without generating liquid compression.
    • 用于预先混合有润滑油的制冷剂气体的空调系统中使用的斜盘式压缩机包括多个气缸孔和活塞,斜盘室,其中使活塞在气缸孔内往复运动的斜盘, 分别与旋转斜盘室连通的多个抽吸通道,与气缸孔连通的抽吸室和排气室以及通过轴密封室与抽吸室连通的至少一个副抽吸室,其中轴密封构件 是适应的 与其底部的旋转斜盘室连通的至少一个吸入通路与副吸入室连通,其他吸入通路与吸入室连通。 停留在斜盘室底部的制冷剂气体和液体油通过与斜盘室的底部连通的吸入通道和排水室流入轴封室。 制冷剂气体和液体油润滑并冷却轴密封室内容纳的轴密封构件,并且由于轴密封构件的操作而被雾化。 然后,雾化的制冷剂气体通过抽吸室流入每个气缸孔。 因此,制冷剂气体在各个气缸孔内被均匀地压缩而不产生液体压缩。

    • A swash-plate type compressor wherein a valve plate confronting an oil reservoir is provided with a vertical oil passage therein which is communicated with the oil reservoir via a relatively large through-bore formed at the lower end thereof, and is also provided with a gas inducing bore of a small diameter at a slightly higher position than the oil level in the oil reservoir for communicating therewith. By means of advantageously utilizing the pressure difference between the inside of the oil reservoir and that of the suction chamber as well as the centrifugal force caused by the rotation of the driving shaft and the swash-plate, the oil in the reservoir can be carried up together with the blow-up gas to each of the places requiring appropriate lubrication through two of the passages for the mixture of gas and oil, tandem arranged, large diametered and then small diametered, bored through the driving shaft, and a plurality of oil distribution bores formed in the boss of the swash-plate.
    • 旋转斜盘式压缩机,其中面对储油器的阀板设置有垂直油路,其中通过在其下端形成的相对较大的通孔与储油器连通,并且还设置有气体 在油藏中的油位稍高的位置处引导小直径的孔,用于与其连通。 通过有利地利用储油器的内部和吸入室的内部之间的压力差以及由驱动轴和旋转斜盘的旋转引起的离心力,可以承载储存器中的油 连同吹出气体一起通过两个用于混合气体和油的通道的需要适当润滑的位置,串联排列,大直径,然后小直径,通过驱动轴钻孔,以及多个油分配 在斜盘的老板中形成的孔。
