摘要： The invention concerns a suction silencer (1) for an encapsulated refrigerant compressor, with an inlet (5), an outlet (6), a damping chamber (7) connecting the inlet (5) and the outlet (6) for sound attenuation, and an equalization chamber connected to the damping chamber (7) for equalizing the pressure of the damping chamber (7), wherein the suction silencer (1) is provided in the operating position for integration in a compressor housing (20) of the refrigerant compressor having a bottom area (21) for reception of an oil sump (26).
To ensure a continuous pressure equalization between the damping chamber (7) and the environment even during start-up of the refrigerant compressor, it is intended in accordance with the invention that the equalization chamber is designed as a first equalization chamber (11) with a first opening (9) for pressure equalization and the suction silencer (1) has a further, second equalization chamber (14) with a second opening (10) for pressure equalization.-

摘要： For a refrigerant compressor, a flexible connection element is provided which connects an end segment of a suction connection piece, which end segment protrudes into the interior of a housing, to a suction sound damper, in particular to a suction opening of the suction sound damper. The end segment itself thereby serves for fastening the flexible connection element onto the end segment and/or the inner wall of the housing.

摘要： End element for the stator of an electric motor of a hermetically sealed refrigerant compressor. The end element includes at least one isolating element, having a ring-like core, to cover an axial end portion of the stator and to isolate a stator core and stator windings. The end element includes several spring holders that extend radially outside the isolating element, each spring holder being adapted to hold a spring for supporting the electric motor in a housing of the hermetically sealed refrigerant compressor. The spring holders are oriented parallel to the axis of the isolating element and an insertion part of each spring holder extends in a first axial direction beyond the neighboring area of the isolating element. The spring holders and the isolating element are integral parts of the end element. The spring holders are tiltable so that an extended part of a spring holder tilts radially inwards.

摘要： A refrigerant compressor includes a hermetically sealed housing and includes a drive unit; wherein the drive unit is arranged in the interior of the housing and is attached, by way of at least one spring element, to at least one mounting region of the housing with mounting action; wherein a first mounting element and a second mounting element are provided; wherein one of the two mounting elements is connected to the drive unit and the other of the two mounting elements is connected to the mounting region. The first mounting element is of sleeve-like form and has an inner wall, and the second mounting element has a bolt-like section, wherein the bolt-like section is received at least in sections in the first mounting element, whereby an overlap region is formed, in which overlap region a gap is formed between the bolt-like section of the second mounting element and the inner wall of the first mounting element.

摘要： An interior permanent magnet rotor, for a drive unit disposed in the interior of a hermetically sealed housing of a refrigerant compressor, whereas the rotor includes a first axial section with permanent magnets, followed by a second axial section without permanent magnets. In order to reduce the risk of a magnetic short-circuit it is provided that the second axial section, adjacent to the first axial section, includes a first axial subsection with a reduced radial dimension not going beyond the permanent magnets in the first axial section, whereas the axial length of the first axial subsection is smaller than the axial length of the first axial section, and the second axial section, adjacent to its first axial subsection, includes a second axial subsection with a radial dimension larger than the reduced radial dimension of the first axial subsection.

摘要： A system includes a refrigerant compressor and an electronic control device therefor. The compressor includes a drive unit and a compression mechanism drivable thereby having a crankshaft-drivable piston. The control device captures and controls, in an open- and/or closed-loop manner, the crankshaft rotational speed and at least approximately captures the piston position. The control device determines an energy evaluation variable difference while the drive unit is switched off proportional to the energy required to perform one crankshaft revolution; at a measurement rotational speed, determines an energy evaluation variable proportional to the rotational energy at the measurement rotational speed; determines the number of crankshaft revolutions remaining, while the drive unit is switched off, until a standstill of the compression mechanism; and checks whether the remaining crankshaft revolutions upon switch-off of the drive unit at a reference piston position enable stopping of the compression mechanism in the suction phase thereof.
