    Abstract: There is provided a rotary compressor including a cylinder an inner peripheral surface of which is defined in an annular shape to define a compression space, provided with a suction port configured to communicate with the compression space to suck and provide refrigerant to the compression space; a roller rotatably provided in the compression space of the cylinder, and provided with a plurality of vane slots providing a back pressure at one side thereinside at predetermined intervals along an outer peripheral surface; a plurality of vanes slidably inserted into the vane slots to rotate together with the roller, front end surfaces of which come into contact with an inner periphery of the cylinder by the back pressure to partition the compression space into a plurality of compression chambers; and a main bearing and a sub bearing provided at both ends of the cylinder, respectively.

    Abstract: A scroll compressor comprises: an orbiting scroll (33) having an orbiting wrap (332), and which performs an orbiting motion; a fixed scroll (32) having a fixed wrap (323) to form a compression chamber (V) of a suction chamber, an intermediate pressure chamber and a discharge chamber, by being engaged with the orbiting wrap; and an offset portion (323b, 332b) formed on a side surface of at least one of the fixed wrap and the orbiting wrap so as to have a distance between the two wraps (δ') greater than an orbiting radius (r) defined as a distance between the two wraps in a concentric state between the orbiting scroll and the fixed scroll.

    Abstract translation: 一种涡旋式压缩机，包括：具有绕动涡卷（332）并且执行绕动运动的绕动涡卷（33） 具有通过与所述绕动涡卷接合而形成吸入室，中间压室和排出室的压缩室（V）的固定涡卷（323）的固定涡卷（32） 以及形成在所述固定涡卷和所述绕动涡卷中的至少一个的侧面上的偏移部分（323b，332b），以使所述两个涡卷之间的距离（δ'）大于定义为的绕动半径（r） 在绕动涡旋盘和固定涡旋盘之间的同心状态下的两个涡卷件之间的距离。
