Abstract

Compressor for refrigerating machines with a cylinder block, in which there is provided at least one piston guided inside a cylinder, which is connected via a connecting rod to the crankshaft supported on the crankcase and therefore less a suction channel connected to the cylinder, which is connected on the side of the inlet with a suction chamber formed for example by the enclosure, a motor box or similar element, from whose lower zone a channel is provided. Oil return, which in particular has a check valve that is closed under excess pressure in the crankshaft chamber, towards the oil collection of the crankshaft chamber, preferably also being provided with a lubrication device for the crankshaft, which forms a oil circuit that includes the oil collector, an oil pump and pipes, characterized in that the oil return channel is connected in an area situated under a depression with a section of conduction, especially of the lubrication device.
