摘要： A refrigerant compressor is provided that can be assembled easily and can quickly discharge lubricating oil that leaks from contact sliding parts of its mechanical seal so as to prevent the oil from turning into sludge around the stationary ring. In a refrigerant compressor (1) in which a mechanical seal (30) which shaft seals the inner side and the outer side of a housing (2) is installed at a portion of the housing (2) through which a rotating shaft (25) penetrates, a mechanical seal (30) comprises a stationary ring (41) securely fastened to the inner circumferential surface of a boss portion (7A), a rotary ring (44) securely fastened to the outer circumferential surface of the rotating shaft (25) to the inside of the stationary ring (41) so as to face the stationary ring, whereby sliding contact is formed between sides of the stationary ring (41) and the rotary ring (44). The inner circumferential surface of the boss portion (7A) to the outside of the stationary ring (41) is provided with an inclined portion (49A) over the entire circumference or at least the gravitationally lower portion of the inner circumferential surface, which enlarges from the stationary ring (41) side toward an oil discharge hole (51) to the outside of the stationary ring (41).

摘要： A scroll compressor comprising a stationary scroll and a revolving scroll, the stationary and revolving scrolls having end plates with a level difference therebetween such that the height increases along the convolutions of the wall toward the center and decreases toward the outer peripheral end, the upper edge of the wall being of stepped shape corresponding to the level difference between the end plates, wherein a clearance is formed between the upper edge of the wall and each end plate and the height of the clearance is greater at the room temperature than during operation. Further, the level difference is provided at a position beyond a traveling angle π (rad) from the outer peripheral end along the direction of convolutions. Further, the end plate of the stationary scroll is formed with a recess, in which a delivery valve is installed. Further, a plate movable in the direction of the axis of revolution of the revolving scroll is installed and a pressing means for pressing the plate is provided. Further, the shape of a connecting wall surface connecting the adjoining ones of the surfaces of the individual end plates is determined by an envelope described by the revolving locus of a connecting edge connecting the adjoining ones of the individual upper edges. Further, there is provided a communication passage which establishes communication between two compression chambers defined by contact between the connecting edge and the connecting wall surface.
摘要翻译： 1.一种涡旋式压缩机，其特征在于，由固定涡旋盘和旋转涡旋盘构成，该固定涡旋盘与回转涡旋盘之间具有高低差的端板，其高度沿着壁向中心的旋转方向增大，随着朝向外周端而减小，所述壁是与所述端板之间的高度差对应的台阶形状，其中在所述壁的上边缘与每个端板之间形成间隙，并且所述间隙的高度在室温下大于在操作期间的高度。此外，在从外周端沿着卷积方向的行进角π（rad）以外的位置设置高度差。此外，固定涡盘的端板形成有凹槽，在该凹槽中安装输送阀。此外，安装可沿回转涡旋盘的回转轴线方向移动的板，并设置用于按压板的按压装置。此外，连接各个端板的相邻表面的连接壁表面的形状由连接相邻的各个上边缘的连接边缘的旋转轨迹描述的包络确定。此外，提供了连通通道，该连通通道建立由连接边缘和连接壁表面之间的接触限定的两个压缩室之间的连通。

摘要： A scroll compressor comprises a fixed scroll having a spiral-shaped wall body, and a swiveling scroll which has a spiral-shaped wall body and revolves while linking together the two wall bodies; the wall bodies have steps, and side faces of two end plates have high and low bottom faces in correspondence with the steps; a chip seal is provided along a join edge which connects top edges on different sides of each step, and a mechanism is provided therebetween to prevent the chip seals from becoming removed from the join edges. Furthermore, in the same scroll compressor, chip seals are provided respectively in two grooves, and join paths are provided respectively between a high-pressure compression chamber, which is formed with the bottom faces as one section, and the two grooves; the pressure inside the high-pressure compression chamber is used as a pressing force for the chip seals.
