REFRIGERANT COMPRESSOR, PISTON OF A REFRIGERANT COMPRESSOR AND PISTON ARRANGEMENT
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 ).
1 . A refrigerant compressor with a cylinder, in which is arranged a piston that is connected to a crankshaft via a connecting rod, the connecting rod having a piston eye, through which a bolt inserted in the piston is guided, wherein the bolt is inserted in a blind bore.
2 . The refrigerant compressor according to claim 1 , wherein the bolt is arranged in the piston with a slide fit.
3 . The refrigerant compressor according to claim 1 , wherein the bolt is held in the piston by means of a perch bolt.
4 . The refrigerant compressor according to claim 3 , wherein the perch bolt extends in parallel to the movement direction of the piston.
5 . The refrigerant compressor according to claim 4 , wherein the perch bolt is arranged in a channel starting from the side of the piston facing the crankshaft.
6 . The refrigerant compressor according to claim 5 , wherein the channel ends with the front side of the piston facing the crankshaft.
7 . The refrigerant compressor according to claim 3 , wherein the perch bolt ends inside the bolt.
8 . The refrigerant compressor according to claim 1 , wherein the bolt comprises a hollow.
9 . The refrigerant compressor according to claim 8 , wherein the hollow starts from an axial end of the bolt and penetrates the bolt on a part of its axial length.
10 . The refrigerant compressor according to claim 8 , wherein the hollow is connected to an oil channel in the connecting rod via a radial channel in the area of the connecting rod.
11 . A piston of a refrigerant compressor according to claim 1 , in which a drilled accommodation of a bolt is made as a blind bore.
12 . A piston arrangement with a connecting rod, a bolt and a piston according to claim 11 .
