Abstract

The invention provides a linear compressor with an oil supply function. The linear compressor with the oil supply function comprises a shell, lubricating oil, a linear motor, a cylinder, a piston, a rotor framework, a resonance spring and the oil supply device. The oil supply device comprises an oil pump and an oil channel. The oil pump comprises an oil cylinder fixed to a rotor, an oil rotor movably arranged on the oil cylinder, and a strong spring and a weak spring separately arranged on the inner side and the outer side of the oil rotor, wherein one end of the strong spring is fixed to a stator of the linear motor, one end of the weak spring is fixed to the oil rotor, and the other end of the weak spring is fixed to the rotor framework. The oil channel comprises an oil suction channel and an oil discharging channel, wherein one end of the oil suction channel is immersed in the lubricating oil at the bottom of the shell, and the other end of the oil suction channel communicates withthe interior of the oil cylinder; and one end of the oil discharging channel communicates with the interior of the oil cylinder, and the other end of the oil discharging channel leads to a gap betweenthe cylinder and the piston. The linear compressor with the oil supply device has the effects that vibration of the rotor framework or an auxiliary rotor is directly used for providing energy for theoil supply device without depending on vibration of a pump body, and thus, oil supply to a linear compressor with an oil supply device and a low-vibration pump body is effectively achieved.

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 with an oil supply device 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 compressor operation, the linear compressor with an oil supply device usually also needs an oil supply device to supply lubricating oil between the piston and the cylinder. [0003] figure 1 It is a s...
