The invention concerns a suction muffler for a hermetic refrigerant compressor with a housing having an inlet and an outlet and limiting at least one muffling chamber, and a gas supply channel located in the muffling chamber between the inlet and the outlet. It is endeavoured to prevent too much oil from remaining in the refrigerant gas flow. For this purpose, the gas supply channel forms a throttling path and ends in the muffling chamber, and that in the area of the inlet of the gas supply channel an oil extraction opening is located, which ends in the muffling chamber.

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.
