Abstract
The invention discloses a sealing chamber of an internal combustion engine. The sealing chamber of the internal combustion engine comprises four arc-shaped molding units, wherein the molding units comprise horizontal bodies and vertical bodies which are molded integrally and arranged vertically; annular bevels are arranged on joints between the outer walls of the horizontal bodies and the vertical bodies; arc-shaped grooves are formed in the joints of the inner walls of the horizontal bodies and the vertical bodies; annular grooves are formed in the bottoms of the vertical bodies; a plurality of through holes are formed in the horizontal bodies; gaps between adjacent molding units are 1-1.5 millimeters; beveled edges are arranged at the two ends of the molding units; the beveled edges are positioned on the vertical bodies. The sealing chamber is simple in structure, is reasonable in design, and is convenient to operate; during assembly, sealing is performed by using elasticity. Through the gaps between adjacent molding units, a compression space can be preserved by compressing during assembly; the beveled edges are arranged for matching with beveled edges another position in the internal combustion engine, so that the sealing performance is enhanced.
Description
Technical field
The present invention relates to internal combustion engine fittings technical field, especially a kind of internal-combustion engine closed chamber.
Background technique
Internal-combustion engine is a kind of dynamic power machine, and it is by making fuel burn at machine intimate, and the heat energy of being released directly is converted to the heat engine of power.Sensu lato internal-combustion engine not only comprises stroke piston combustion engine, rotary engine and free piston engine, also comprise the gas turbine of rotary vane type, jet engine etc., but usually said internal-combustion engine refers to internal-combustion piston engine.Internal-combustion piston engine is the most general with reciprocating piston type.Internal-combustion piston engine, by fuel and air mixing, burns in its cylinder combustion, and the heat energy discharged makes the combustion gas producing High Temperature High Pressure in cylinder.Combustion gas is expanded and is promoted piston work done, then mechanical work is exported by connecting rod or other mechanisms, drives follower work.Part very crucial when closed chamber is internal-combustion engine assembling, traditional closed chamber is structure as a whole, and sealing effect is poor.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, the internal-combustion engine closed chamber of good sealing effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal-combustion engine closed chamber, comprises the forming unit of four arcs, and forming unit comprises one-body molded vertically disposed horizontal body and vertical body; Described horizontal body and vertical body outer wall connecting part are provided with annular slope, and horizontal body and vertical inner body wall connecting part are provided with the curve bath be bent upwards; Described vertical body bottom portion offers circular groove, and horizontal body is provided with multiple through hole; Between described adjacent forming unit, gap is 1-1.5mm, and forming unit two ends are provided with slope, and groove is positioned in horizontal body.
Further, described through hole is by comprising large through-hole, middle through hole and small through hole, and large through-hole is evenly distributed in horizontal body, and horizontal body two ends offer middle through hole and small through hole.
Further, described middle through hole and small through hole are between two large through-holes, and middle through hole is between small through hole and large through-hole.
Further, the second annular slope is provided with bottom described horizontal body inwall.
The invention has the beneficial effects as follows: structure of the present invention is simple, and reasonable in design, easy to operate, comprise the forming unit of four arcs, each forming unit is 1/4th sections, possesses elasticity, utilizing this elasticity to seal when assembling.When to arrange gap etc. between adjacent forming unit be to assemble, compressing can the space of preparatory compression, and arranging groove is to coordinate another position in internal-combustion engine also to have groove, improves sealability.
