Embodiment Construction

[0018] Refer below figure 1 and figure 2 The specific implementation of the oil supply mechanism of the linear compressor of the present invention will be described in detail.

[0019] Such as figure 1 As shown, the linear compressor has a casing 1 , and a motor body 2 and an oil supply mechanism 3 are accommodated in the casing 1 . A recess is formed at the bottom of the housing 1, and lubricating oil is stored in the recess, and symbol 6 in the figure indicates the liquid level of the lubricating oil. The oil supply mechanism 3 is connected to the motor body 2 through an oil supply pipe 4 to deliver lubricating oil to the motor body 2 . The motor body 2 has a housing 21 , and the housing 21 is supported on the inner wall of the housing 1 by a plurality of springs. The casing 21 is provided with a cylinder 11, a piston 12, a compression chamber 18, an exhaust valve 19, an inner stator 14, a coil 17 placed in the inner stator 14, an outer stator 15, a mover 16 and a mover...

Abstract

The invention provides an oil supply mechanism of a linear compressor. The linear compressor is provided with a shell. A motor body and the oil supply mechanism used for supplying oil to the motor body are contained in the shell. The oil supply mechanism comprises an oil cylinder and an oil piston arranged in the oil cylinder. The oil cylinder is fixed to the motor body and connected with the motor body through an oil supply pipe. The oil piston is fixed to the shell. The oil cylinder and the motor body are arranged in linkage. The oil cylinder moves relative to the oil piston with the assistance of motion of the motor body, so that the oil supply mechanism supplies the oil through the oil supply pipe. It can be guaranteed that the oil cylinder moves relative to the oil piston, motion is reliable, and therefore the oil supply effect is guaranteed.

Description

technical field [0001] The invention relates to an oil supply mechanism of a linear compressor. Background technique [0002] At present, the oil supply mechanisms of linear compressors mainly include two types: the first is the oil pump assembly connected to the internal motor structure of the compressor, which includes valve plates, gaskets, oil circuit pistons and spring assemblies, and the internal motor The vibration drives the spring inside the oil pump connected to it and the oil piston to vibrate to oil. But the structure is more complex and difficult to install; the second is the oil pump assembly connected to the internal motor structure of the compressor. The assembly includes multiple valve plates and gaskets, and the vibration of the internal motor drives the oil pump connected to it. Oiling is done slowly. Although the structure is relatively simple, the oiling effect is poor. [0003] In addition, Chinese patent publication CN1548736A discloses an oil suppl...
