Problems solved by technology

[0009] However, in the hermetic compressor of the prior art as described above, there is a problem that the above-mentioned piston 7 rapidly performs linear reciprocating motion inside the compression chamber 6'.
Therefore, the entire inner wall of the compression chamber 6' and the outer circumference of the piston 7 rub against each other, and this friction increases the input power of the compressor, causing the problem of a decrease in the efficiency of the compressor.

Abstract

The invention discloses a closed-style compressor, which comprises the following parts: specific shaped piston 30, cylinder 20, compression chamber 22, guiding face 33, drainage hole 25 and bulk space 36, wherein the guiding face 33 is formed around the outer column face of piston and composed of piston length direction symmetrically, which slides in the cylinder 20 and compression chamber 22 within the more than 40 deg arc scale of piston length direction central axle; the bulk space 36 engages the drainage hole 25 of working fluid from compression chamber 22 in front of piston projection part, whose front displays flush conical shape deflecting from the length direction center of piston 30. The invention can improve the compressor working efficiency.

Description

technical field [0001] The present invention relates to a hermetic compressor, and more specifically relates to the invention of a hermetic compressor that compresses a working fluid during the linear reciprocating motion of a piston inside a compression chamber of a cylinder. Background technique [0002] exist figure 1 The structure of a prior art hermetic compressor is illustrated in a cross-sectional view. [0003] First, the airtight container 1 is composed of an upper container 1t and a lower container 1b, and forms an airtight space inside. A frame 2 is arranged inside the airtight container 1 . A stator 3 is fixed on the bottom of the frame 2, and the stator 3 is supported inside the airtight container 1 by a spring 2S. The rotor 4 is designed to pass through the center of the stator 3 and rotate with the stator 3 according to electromagnetic action. The rotor 4 is integrally connected with the crankshaft 5 penetrating through the central part of the frame 2 to r...
