  • Patent number: 8342824
    Abstract: A piston compressor, particularly a refrigerant compressor includes a compression chamber in a compressor block, the compression chamber being delimited by a cylinder head (10), the cylinder head (10) comprising at least one valve plate arrangement with at least one suction valve (23, 24) and at least one pressure valve (21, 22), as well as a valve cover (12). To achieve low manufacturing costs, though maintaining a good efficiency, the valve plate arrangement (16) is formed by a carrier plate (17) that comprises the suction valve (23, 24, 26, 27) and the pressure valve (18, 19, 21, 22) and is connected by at least one gas-tight connection seam (28, 31) to the valve cover (12), the connection seam (28, 31) separating a suction area (32) and a pressure area (29, 30) from one another and sealing at least the pressure area (29, 30) towards the outside.

  • Patent number: 8192174
    Abstract: The invention concerns a refrigerant compressor (1), in particular a semi-hermetic refrigerant compressor, with a compressor block (5) comprising several cylinders arranged in a star shape, a motor, whose rotor is unrotatably connected to a crankshaft (11) that comprises a crank pin (22) and is supported in a bearing (13) in the compressor block (5), and a piston in each cylinder, each piston being connected via a connecting rod (23) to the crank pin (22), the connecting rod (23) comprising a bearing pad (24) that rests on the crank pin (22), the bearing pads (24) of all connecting rods (23) being held on the crank pin (22) by means of a ring arrangement (25). It is endeavored to keep the load on the crankshaft small. For this purpose, each connecting rod (23) has a power application point (49) at the crank pin (22), which is displaced in the direction of the bearing (13) in relation to the axial center of the crank pin (22).

  • Patent number: 8079830
    Abstract: The invention concerns a refrigerant compressor (1), particularly a semi-hermetic refrigerant compressor, with a housing (2), having in its bottom part (3) an oil sump (4), a compressor block (5) having at least one cylinder (6), in which a piston (7) is arranged, a crankshaft (11), which is supported in the compressor block (5) and in driving connection with the piston (7), and an oil pump arrangement (27), which is at least partly submerged in the oil sump. Also with varying speeds, good oil lubrication must be ensured. For this purpose, the crankshaft (11) has at its lower end a diameter extension (19), through which an oil channel (35) extends eccentrically to the crankshaft axis (36), said channel (35) connecting the oil pump arrangement (27) to a closed oil pressure chamber (21) between the crankshaft (11) and the compressor block (5), said chamber (21) being connected to the inside (37) of the housing (2) via a vent path (40, 41).

  • Patent number: 6666669
    Abstract: The invention concerns a scroll compressor with at least one fixed displacement element, at least one movable displacement element, which is guided in relation to the fixed displacement element with an orbiting movement, and a gear arrangement, which ensures a non-rotational movement of the movable displacement element and comprises an axial bearing, via which the movable displacement element is supported in an axial direction.

  • Patent number: 6648617
    Abstract: The invention relates to a method for compressing a compressible medium, in which at least two displacement elements, each having at least one limiting face extending helically in the cross section, are orbited in relation to each other under formation of at least one chamber, the volume of the chamber being changed by the orbiting movement, performing a cycle with a suction phase, a compression phase and a discharge phase, the chamber being opened and forming a suction chamber during the suction phase. It is endeavoured to improve the thermodynamic conditions during compression of a compressible medium. For this purpose, for the duration of the suction phase, the suction chamber is reduced by a volume limiting element in such a way that at the end of the suction phase the chamber has a volume of at least 90% of a maximum volume appearing during the suction phase.
