Embodiment Construction

[0020] The present invention is described in more detail below in conjunction with accompanying drawing:

[0021] A reciprocating internal combustion air compressor includes: an internal combustion engine; the internal combustion engine includes a flywheel 1, a crank 2, a crankshaft 3, a connecting rod 4, a piston 5 and a cylinder 6. The piston of the internal combustion engine has a three-stage structure, which are respectively a large diameter section at the upper end, a tapered transition section at the middle and a small diameter section at the lower end; Matching, the small diameter section at the lower end partially stretches out of the cylinder liner. The small diameter section at the lower end has a ring groove for installing a piston ring, and the piston ring is installed on the ring groove. The side wall of the cylinder liner of the internal combustion engine is provided with a compressed air inlet and a compressed air outlet.

Abstract

A reciprocating internal combustion air compressor comprises an internal combustion engine. A piston of the internal combustion engine is of a three-section type structure, namely the upper-end large-diameter section, the middle conical transition section and the lower-end small-diameter section. The upper-end large-diameter section of the piston is matched with the inner wall of an air cylinder of the internal combustion engine, the lower-end small-diameter section of the piston is matched with the lower end of the air cylinder, and the lower-end small-diameter section partially extends out of a cylinder sleeve. A ring groove for mounting a piston ring is mounted on the lower-end small-diameter section. The piston ring is mounted on the ring groove. A compressed air inlet and a compressedair outlet are formed in the side wall of the cylinder sleeve of the internal combustion engine. According to the reciprocating internal combustion air compressor, the air compressor is fused with the structure of the internal combustion engine, the occupied space of the air compressor unit is reduced greatly, no coupling is needed for torque transmission, the shaft system structure is simplifiedgreatly, the operating reliability and the air compression efficiency are improved, and mounting is more convenient.

Description

technical field [0001] The invention relates to an air compressor device, in particular to a reciprocating internal combustion air compressor. Background technique [0002] High-pressure air plays an important role on ships. For example, the start-up of internal combustion engines and blowing work are inseparable from high-pressure air, and the common way to obtain high-pressure air is to use an air compressor. So the air compressor is an essential auxiliary machinery on board. Reducing the volume of marine auxiliary engines is of great significance to improving the power density of ships. [0003] At present, the structural forms of air compressors are mainly cascade reciprocating air compressors and star reciprocating air compressors. Regardless of the structure of the air compressor, it needs a prime mover when it is running. Generally, a motor or an internal combustion engine is used to drive the air compressor to work. The traditional air compressor needs to be drive...
