The invention concerns a refrigerant compressor arrangement () with a housing () comprising a suction opening (), a compressor (), which is arranged in the housing (), and is connected to the suction opening (), and a suction connection () that is fixed at the housing (), and comprises a housing section () and a tube section (), the housing section () being connected to the suction opening () and the diameter of the tube section () being different from the diameter of the housing section (). With such a refrigerant compressor arrangement, it is endeavoured to keep the dimensions small. For this purpose, in the longitudinal direction of the suction connection () the housing section () and the tube section () overlap each other and are connected to each other by a corrugated area () with at least one radial corrugation.

The invention concerns a piston compressor cylinder arrangement (), particularly for a hermetically enclosed refrigerant compressor, with a cylinder body () and a cylinder head arrangement (), the cylinder body () having a first front side () in the area of the cylinder head arrangement () and a second front side () at the other end. It is endeavoured to manufacture such a cylinder arrangement in a cost-effective manner without having to fear for a deformation during mounting. For this purpose, a cup-shaped mounting sleeve () surrounds the cylinder body () over its full axial working length with a radial distance on all sides.

Piston compressor cylinder arrangement, particularly for a hermetically enclosed refrigerant compressor

The invention concerns a refrigerant compressor arrangement with a compressor having a suction inlet, a casing, in which the compressor is located, a suction socket, which is in communication with the casing, a suction opening in the casing, which is connected with the suction socket, and a telescopic pipe, which is located between the suction inlet and the suction opening in the casing. It is endeavored to manufacture a refrigerant compressor arrangement in a cost-effective manner. For this purpose, the suction opening is surrounded by a drawing through in the casing wall, whose inner wall forms a sliding surface for the telescopic pipe.

Refrigerant compressor arrangement

The invention concerns a method for mounting a drive shaft () of a compressor, particularly a hermetical refrigerant compressor, which has a motor with a stator () and a rotor (), connected with the drive shaft () and located in a rotor opening () of the stator (), a first bearing support () and a second bearing support () being connected with the stator (), a first bearing () for the drive shaft () being mounted in the first bearing support () and a second bearing () for the drive shaft () being mounted in the second bearing support (). It is endeavoured to provide a method for mounting a drive shaft, in which the use of components with relatively large manufacturing tolerances will still result in a good alignment of the drive shaft in relation to the stator. For this purpose, at least the first bearing support () is provided with a positioning stop for the first bearing () after mounting the first bearing support () on the stator ().

Method for mounting a drive shaft of a compressor

The invention concerns a rotor arrangement for an electrical drive motor of a compressor, particularly a refrigerant compressor, with a rotor having a rotor lamination of stacked sheet plates, and a shaft, which is inserted in an axial recess of the rotor lamination and is unrotatably connected with the rotor lamination, the recess being formed by openings in adjacent sheet plates. It is endeavoured to simplify the manufacturing of such rotor arrangements. For this purpose, it is ensured that openings of different sizes are provided in the sheet plates, at least two sheet plates forming a first group, each having an opening, which is smaller than the cross-section of the shaft, the remaining sheet plates forming a second group, each having an opening, which is larger than the cross-section of the shaft.

The invention concerns a piston compressor with a piston, which is connected with a crank pin of a drive shaft via a connecting rod having a longitudinal channel. It is endeavored to make the manufacturing of a piston compressor cost effective. For this purpose, it is ensured that the shaft of the connecting rod is made as a sheet metal pipe.

Piston compressor

The invention concerns a piston arrangement having a piston with a piston head and a piston skirt with a circumferential surface, and a connecting rod, which is connected with the piston via a ball joint comprising a ball, and penetrated by an oil supply channel, which is connected with a bearing surface of the ball joint.

Piston arrangement

The invention concerns a piston arrangement having a piston with a piston head and a piston skirt and a connecting rod, which is connected with the piston via a ball joint arrangement comprising a ball, the ball being held in the piston by means of a safety element.

The apparatus includes a laminated core that has frontal end faces and slots with a winding extending in the slots. An electrical insulating end plate is provided adjacent at each frontal end face and adjacent to the winding heads of the winding. At least one of the end plates has a connecting box with a plurality of clamps for the ends of the windings and the terminal of a motor protection device.
