Abstract

The invention belongs to the technical field of a linear compressor, in particular to a device for supplying oil for a friction part between a cylinder and a piston in the linear compressor. The oil supply device is arranged at the bottom of a stand of the linear compressor in a closed container; the stand is internally provided with an oil discharge channel; an oil inlet hole of the oil discharge channel is sequentially provided with a baffle and an oil cylinder in a horizontal way; a first spring and a second spring which are deformed by pre-pressing are respectively arranged at the two ends of the piston arranged in the oil cylinder; the bottom of the baffle is provided with an oil inlet channel connected with the oil cylinder; an oil absorption valve is arranged at the part where the oil inlet channel is connected with the oil cylinder; and an oil drain valve is arranged at the part where an oil channel of the baffle is connected with the oil discharge channel. The oil absorption valve is arranged at the wider part where the oil inlet channel is connected with the oil cylinder, and the oil drain valve is arranged at the wider part where the oil channel of the baffle is connected with the oil discharge channel, so that the oil absorption valve and the oil drain valve which are installed in this way are simple in structure and easy to manufacture and assemble, and the processing technology of the oil absorption valve and the oil drain valve can be simplified.

Description

technical field

[0001] The invention belongs to the technical field of linear compressors, in particular to a device for supplying oil to friction parts of a cylinder and a piston in a linear compressor. Background technique

[0002] The compressor used in traditional refrigeration equipment uses a rotating motor, plus a set of crankshaft and connecting rod transmission mechanism that converts the rotating motion into reciprocating motion to push the piston to compress the refrigerant gas. Since the manufacturing of each component is complicated and friction will be generated between the components, the efficiency of the compressor is reduced and the power consumption is large.

[0003] Linear compressors use permanent magnets and coils to form a linear motor instead of a crank mechanism and a rotary motor to make the piston reciprocate to compress the refrigerant. Linear compressors reduce friction between components by reducing the number of transmission components. In o...
