  • Publication number: 20100034679
    Abstract: The invention concerns a refrigerant compressor with a cylinder, in which is arranged a piston (5) that is connected to a crankshaft via a connecting rod (14), the connecting rod (14) having a piston eye (18), through which a bolt (17) inserted in the piston (5) is guided. With such a refrigerant compressor, it is endeavoured to achieve a good efficiency. For this purpose, the bolt (17) is inserted in a blind bore (19).

  • Publication number: 20090110585
    Abstract: The invention concerns a refrigerant compressor arrangement with a compressor unit (2) supported in a case by means of springs (12) and comprising at least one bolt (26) with a bolt head (25), a holder (23) being arranged between the compressor unit (2) and at least one spring (12), the holder (23) having in its front a recess, in which the bolt head (25) engages, and which is connected to the spring (12). It is endeavoured to reduce the noise generation during operation of the refrigerant compressor arrangement. For this purpose, the bolt head (25) is arranged in the recess (24) with lateral clearance (34).

  • Patent number: 7421940
    Abstract: 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.

  • Patent number: 6845843
    Abstract: 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 (7), 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.

  • Patent number: 6715582
    Abstract: The invention relates to a suction muffler for a hermetically enclosed compressor, with a housing having a first part with an outlet channel and a second part with an inlet channel, flow conducting means being arranged between the outlet channel and the inlet channel, said means forming, together with the inlet channel and the outlet channel, a flow path, and a filter being arranged in the outlet channel. Further improvements of the noise damping are endeavored. For this purpose, the filter has a sieve-like embodiment and that the flow path comprises at least one second filter with a sieve-like embodiment.

  • Patent number: 6688432
    Abstract: 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.
