A rotary piston compressor including a main housing part composed of a plurality of interconnected components one of which has a trochoidal two arc-shaped inner surface forming a race way, and a triangular piston rotatable in the eccentric of an eccentric shaft. The corners of the triangular piston are in continuous sliding contact with the race way. The components are surrounded by a capsule housing which on one side of the compressor has a pressure connection arranged in a dome-shaped cover. This cover includes a hood separating the high pressure section from the low pressure section. The cover is connected to the hood by a central member forming a connection for the inlet conduit. The hood sealingly engages a step in the adjacent housing component. The capsule housing has an annular shoulder by means of which under tension it extends around the outer rim portion of the component adjacent to the cover, then extends over the other components, and is bent over the outer peripheral rim portion of the component farthest from the cover. The piston has a side wall on only one side and is pot-shaped while the counter weight for the piston is arranged in the latter. |
