Problems solved by technology
[0004] In the above oil supply structures, the inertia of the parts is needed to realize the relative movement of the piston and the oil cylinder. Since the mass of the oil cylinder and the oil piston in the linear compressor is very small, the inertia is also small, and the relative movement caused by the inertia is small. The oil pumping ability is poor, and the flow rate of lubricating oil pumped is low, so it is difficult to meet the needs of lubrication
However, if the quality of the oil pump assembly is increased, its volume will be increased, and precious space will be wasted.
In addition, because some parts of the above structure are not fixed, it is difficult to install and has low reliability.

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0023] Such as figure 1 As shown, the compressor 100 has a housing 13, and the motor body 101 of the linear motor is supported in the housing 13. The motor body 101 has a cylinder 2 supported by a support flange 3, and the cylinder 2 is horizontally arranged (its axis is in the horizontal direction ), a piston 1 is provided in the cylinder 2, and a permanent magnet 10 is connected to the piston 1. An inner stator piece 9 is arranged on the inner peripheral side of the permanent magnet 10, and an outer stator piece 11 is arranged on the outer peripheral side. After the compressor is energized, the permanent magnet 10 produces relative motion under the action of the alternating magn...

The invention discloses a linear compressor and an oil supply device thereof. The linear compressor comprises a shell and a motor body located in the shell. The oil supply device comprises an oil pump, the oil pump comprises an oil cylinder and an oil piston which are matched with each other, the oil cylinder and the oil piston are connected to the shell and the motor body of the linear compressor respectively and fixedly, and the oil cylinder is fixedly connected to the shell of the linear compressor through screws. The oil cylinder and the oil piston of the oil pump are connected to the shell and the motor body of the linear compressor respectively and fixedly, relative movement of the oil cylinder and the oil piston is achieved through relative vibration between the shell and the motor body of the linear compressor, the oil supply device does not need to rely on inertia in a working process, and the reliability is high. Besides, due to the fact that the oil cylinder and the oil piston are connected to the shell and the motor body of the linear compressor respectively and fixedly, no non-fixed component exits, and installation is convenient.
Description
technical field [0001] The invention relates to the technical field of linear compressors, in particular to an oil supply device for a linear compressor and a linear compressor including the oil supply device. Background technique [0002] The linear compressor is used to suck the compressed fluid into the cylinder, and use the linear driving force of the linear motor to make the piston reciprocate linearly in the cylinder to compress the fluid, and then discharge the compressed fluid. When the compressor is working, the piston reciprocates at high frequency in the cylinder, and there is friction between the piston and cylinder, which will consume a certain amount of power, and may also cause impurities such as wear debris, which will aggravate the wear of the piston and cylinder, resulting in increased gas leakage. , the efficiency of compressed gas is reduced, and the aggravation of wear will not only cause damage to the piston and cylinder, but also may cause serious prob...
