The invention concerns a piston compressor, particularly a hermetically enclosed refrigerant compressor, with at least one cylinder a piston reciprocating in said cylinder, the piston being connected with a driving rod via a piston pin and having in its outer jacket surface a circumferential lubrication groove, the piston pin having a longitudinal bore, which is connected with a lubricant source. It is endeavoured to improve the lubrication. For this purpose, the longitudinal bore is open downward in the gravity direction and has a ventilation opening upward.

The invention concerns a suction muffler for a refrigerating machine with a housing, in which at least one chamber is arranged and which has an inlet opening (), an outlet opening and an oil discharge opening. It is endeavoured to avoid that too much oil remains in the chamber. For this purpose, an oil collecting room is arranged to be connected to the bottom end of the chamber, the oil discharge opening being arranged at the bottom end of said oil collecting room.

The invention concerns a piston compressor, particularly a hermetically enclosed piston compressor, with a housing, in which a motor is arranged, the motor having a crankshaft with a vertically standing crank pin that has in its upper front side an opening, which is connected with an oil supply arrangement. It is endeavored to reduce an external oil circulation. For this purpose, the opening is provided with a limiting arrangement, which limits an axially directed movement of lubricating oil from the opening to a predetermined area.
