Abstract
The utility model discloses a connector connecting the diesel head with the sucker, which comprises a cylinder head body, a sucker connected with the intake pipe of the cylinder head body, and the sucker and the intake pipe are in the cuttage grafting of liquid sealing. The sucker comprises a sucker body and a connector fixed onto the sucker body, and between the perimeter of the connector and the surface of the intake pipe a gland bush is arranged. Owning to the flexible coupling formed between the sucker and the cylinder head body, the flexible coupling can not only be used to solve the problem of difficulty in installation caused by the accumulated manufacturing errors of the connector, but also reduce the stress generated in the joint in use, thereby preventing the greater loss of the fuel caused by the cylinder head.
Description
Technical field
The utility model relates to Diesel Engine Technique Field, relates in particular to the connection set of a kind of cylinder cover for diesel engine and oil inlet pipe.
Background technique
The cylinder head oil inlet pipe is the unique path that lubrication system is supplied with cylinder cover for diesel engine machine oil, is mainly used in friction pairs such as lubricated cylinder head inner rocker arm, rocker arm bracket.Higher because of the need oil pressure, lubricating point is far away according to the oil pump end again, so the general caliber of this oil inlet pipe is thinner.Traditional cylinder cover for diesel engine machine oil pipe adopts hard connecting modes such as screw thread.In installation process, because diesel engine is made up of numerous component, after each component assemble, might cause uncontrollable cumulative error, thereby make the pipe fitting between the component connect appearance phenomenon not in place.Even assembling the time does not go wrong, also might using process afterwards in, make hard connection tube brakes cause leakage of oil because of distortion produces stress, so produce because of lose that oil causes than major break down.
The model utility content
Technical problem to be solved in the utility model is: the connection set that a kind of cylinder cover for diesel engine and oil inlet pipe are provided, the installation difficulty that its oil inlet pipe and the accumulation foozle of not only being convenient to being connected of cylinder head body to eliminate because of connected element cause, and in use its joint is not easy to produce stress, thereby can prevent the greater loss that cylinder head mistake oil causes.
For solving the problems of the technologies described above, the technical solution of the utility model is: the connection set of cylinder cover for diesel engine and oil inlet pipe, comprise the cylinder head body, with the oil inlet pipe that the oil suction chamber of described cylinder head body is connected, the oil suction chamber liquid sealing of described oil inlet pipe and described cylinder head body is pegged graft.
Described oil inlet pipe comprises oil inlet pipe body and the plug connector of fixedlying connected with described oil inlet pipe body, is provided with seal arrangement between the side face of described plug connector and the housing surface of oil suction chamber.
The oil suction chamber of described cylinder head body is a unthreaded hole.
Because the oil suction chamber liquid sealing of oil inlet pipe and described cylinder head body is pegged graft, thereby oil inlet pipe and cylinder head body form in the joint and are flexible coupling, this form that is flexible coupling not only is convenient to eliminate the installation difficulty that the accumulation foozle because of connected element causes, and in use its joint is not easy to produce stress, thereby can prevent the greater loss that cylinder head mistake oil causes.In addition, the oil suction chamber of cylinder head body is a unthreaded hole, with respect to the tapped hole in the known technology, has simplified the processing technology of cylinder head body, has reduced manufacture cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a sectional view.
Embodiment
The connection set of cylinder cover for diesel engine and oil inlet pipe as shown in drawings, comprises cylinder head body 3 and oil inlet pipe, and described oil inlet pipe comprises oil inlet pipe body 1 and the plug connector 2 of fixedlying connected with described oil inlet pipe body 1.The outer circumferential face of described plug connector 2 is provided with annular groove, and this annular groove is embedded in O type rubber seal 4.
The oil suction chamber 5 of cylinder head body 3 is unthreaded holes, and plug connector 2 inserts oil suction chamber 5, and the O type rubber seal 4 that is mounted thereon forms liquid sealing with the housing surface of oil suction chamber 5.The oil suction chamber of cylinder head body is made as unthreaded hole, with respect to the tapped hole in the known technology, has simplified processing technology, has reduced manufacture cost.
The quantity of O type rubber seal 4 is one, in order to strengthen sealing effect, can be made as two or more.
In addition, liquid sealing device between the oil suction chamber 5 of plug connector 2 and cylinder head body 3 also can adopt other Sealings such as outside framework oil seal, as long as its joint can form liquid sealing and allow plug connector 2 and oil suction chamber 5 to produce relative displacement, promptly be flexible coupling, this form that is flexible coupling not only is convenient to eliminate the installation difficulty that the accumulation foozle because of connected element causes, and in use its joint is not easy to produce stress, thereby can prevent the greater loss that cylinder head mistake oil causes.
