Abstract
The utility model discloses a cylinder cover of a diesel engine, which comprises a cylinder cover body and a cylinder cover housing, an air valve is arranged in the cylinder cover body and comprises an air inlet valve and an exhaust valve which are arranged in parallel, and the air outlet ends of the air inlet valve and the exhaust valve extend into the cylinder cover housing and are respectively provided with a pressing block, and a spring is arranged below each pressing block. As for the cylinder cover of the diesel engine, an air valve guide pipe used in the original traditional cylinder cover is omitted, and the air valve is integrated with the cylinder cover, so that the structure is more compact, the arrangement of a fuel spray nozzle close to the center of the cylinder is benefited, the burning sufficiency is improved, the coaxiality of an air valve guide pipe hole and a seat retainer is improved, and the sealing property of the air valve is improved.
Description
Technical field
The utility model relates to a kind of diesel engine cylinder cover.
Background technique
On the intake valve and exhaust valve that cylinder of diesel engine covers, be typically provided with valve guide bushing at present, guiding and protection valve when being used for valve motion; prevent wearing and tearing, because valve guide bushing and valve need assembling, therefore; valve and valve guide bushing all need to process; guarantee concentricity between the two, just can guarantee the sealing of valve, in use for some time; valve guide bushing has worn and torn and has changed again; so both improved fabricating cost, and increased workload again, operation is trouble also.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of compact structure, simple is provided, the diesel engine cylinder cover that concentricity is better, help improving valve sealing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of diesel engine cylinder cover, comprise cylinder body and cylinder head cover, be provided with valve in the cylinder body, described valve comprise be arranged side by side, the outlet side puts in intake valve and exhaust valve in the cylinder head cover, the outlet side of intake valve and exhaust valve is respectively equipped with briquetting, and briquetting has spring.
Further, the inlet end of described intake valve and exhaust valve is respectively equipped with the air valve seat ring that is structure as a whole with cylinder body.
The beneficial effects of the utility model are: the utility model has been cancelled the valve guide bushing of original use, realizes the integrated of valve and cylinder cap, can make structural design compacter, helps the oil nozzle layout and draws close to cylinder axis, improves the adequacy of burning; Help valve guide hole and seat ring coaxality and improve, improve the sealing of valve.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. cylinder bodies, 2. cylinder head covers, 3. intake valves, 4. exhaust valves, 5. briquettings, 6. springs, 7. air valve seat rings among the figure
Embodiment
In conjunction with the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of diesel engine cylinder cover as shown in Figure 1, comprise cylinder body 1 and cylinder head cover 2, be provided with valve in the cylinder body 1, described valve comprise be arranged side by side, the outlet side puts in intake valve 3 and exhaust valve 4 in the cylinder head cover 2, the inlet end of intake valve 3 and exhaust valve 4 is respectively equipped with the air valve seat ring 7 that is structure as a whole with cylinder body 1, the outlet side of intake valve 3 and exhaust valve 4 is respectively equipped with briquetting 5, briquetting 5 has spring 6, after briquetting 5 is depressed intake valve 3 and exhaust valve 4, can utilize the Push And Release of the spring-back force realization valve of spring 6.
The utility model originally is enclosed within laterostigmatal valve guide bushing owing to having cancelled, cylinder body 1 has been selected the high-abrasive material making for use, realizes the integrated of valve and cylinder body 1, can make structural design compacter, help the oil nozzle layout and draw close, improve the adequacy of burning to cylinder axis; Help valve guide hole and seat ring coaxality and improve, improve the sealing of valve.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
