A linear compressor with an oil supply device comprises a shell; lubricating oil stored at the bottom of the shell; a linear motor and a cylinder which are fixed in the shell, wherein the linear motoris composed of a stator, a coil and a permanent magnet; a piston driven by the linear motor and doing linear reciprocating motion in the cylinder; a rotor frame connected with the permanent magnet onthe linear motor and the piston; and a stator spring plate fixed to the stator; and a resonant spring connected between the rotor frame and the stator spring plate. The linear compressor is characterized in that the linear compressor with the oil supply device further comprises the oil supply device; the oil supply device comprises an oil cylinder fixed to the stator spring plate; an oil rotor movably arranged in the oil cylinder; and an oil spring arranged at the exterior of the oil cylinder in a sleeved manner and used for supporting the oil rotor elastically. The linear compressor has theeffects of the simple structure and convenient installation. The linear compressor works stably, and the operation reliability of the linear compressor is improved.
Description
technical field [0001] The invention belongs to the technical field of compression machinery, in particular to a linear compressor with an oil supply device. Background technique [0002] The linear compressor is a device that uses a linear motor to drive the piston to reciprocate, thereby compressing the gas sucked into the cylinder and then discharging it. Compared with the traditional reciprocating compressor, the linear compressor with an oil supply device cancels the structure of the crankshaft connecting rod, reduces the number of transmission structures, and also reduces the friction between various transmission components. However, there is still a friction surface between the piston and the cylinder. In order to ensure the reliability of the linear compressor, it is usually necessary to supply lubricating oil between the piston and the cylinder through an oil supply device. [0003] figure 1 It is a sectional view of the longitudinal structure of a linear compress...
