Abstract
- a compressor shell (100);
- a pump unit (10) located within the compressor shell (100), said pump unit (10) comprising:
-- a cranktrain (200) with a crankshaft (210), a counterweight (225), a crankpin (220), a connecting rod (230) and a piston (240;
-- a crankcase (300) with a cylinder housing (310), wherein a cylinder (320) for reciprocating movement of the piston (240) is located, and wherein the crankshaft (210) is rotatably mounted inside a main bearing section (302),
-- an electric drive unit (400) with a stator (420) and a rotor (410), the rotor (410) being fixed to the crankshaft (210) ;
-- wherein the crankshaft (210) is axially supported by a ball bearing (201) on the crankcase (300).
