Description
Technical field
The utility model relates to technical field of engines, and in particular to a kind of novel camshaft cylinder cap.
Background technology
Camshaft is one of five big core members of engine, its effect is unlatching and the closed action of control valve, though
So in four-stroke engine the rotating speed of camshaft be bent axle half, but usually its rotating speed it is still very high, and need hold
By prodigious torque, and valve motion rule is related to the power and service performance of engine, therefore camshaft is in engine
In occupation of highly important status in design process.
It, can be by cam according to its particularity and functionality under normal conditions because camshaft needs to bear prodigious torque
Axis designs on cylinder body, and camshaft structure will not be designed on corresponding cylinder cap, will greatly increase engine complete machine in this way
Weight, the distance between camshaft and valve can also increase, and the tappet of valve and the weight of tappet and length also can accordingly increase,
It increases manufacturing cost and difficulty of processing.Based on this, it is particularly necessary to design a kind of novel camshaft cylinder cap.
Utility model content
In view of the shortcomings of the prior art, the utility model aims to provide a kind of novel camshaft cylinder cap,
Simple in structure, reasonable design, engine structure is compacter, reduces the weight and assembly difficulty of engine, reduces manufacture and adds
Work cost increases stability, highly practical, use easy to spread.
To achieve the goals above, the utility model is to realize by the following technical solutions：A kind of novel camshaft
Cylinder cap, including air intake duct, oil hole, camshaft hole, water channel hole, inlet valve seat, delivery valve seat, exhaust duct are set on front side of lid
It is equipped with air intake duct, exhaust duct is provided on rear side of lid, the both sides of lid are provided with oil hole, camshaft hole, air intake duct, oil duct
Hole, exhaust duct are connected to the combustion chamber in lid, and lid upper side is additionally provided with water channel hole, inlet valve seat, delivery valve seat.
Preferably, the inlet valve seat, delivery valve seat interleaved are arranged on lid.
The beneficial effects of the utility model：(1) the distance between camshaft and valve are shortened, the tappet of valve is omitted
And tappet, overall structure is compacter, reduces main screw lift and volume；
(2) casting cost and processing cost are reduced, difficulty of processing is reduced；
(3) the whole transmission ratio for improving camshaft, increases the stability of engine.

Fig. 5 is the structural schematic diagram of the utility model combustion chamber.
Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Fig.1-5, present embodiment uses following technical scheme：A kind of novel camshaft cylinder cap, including air inlet
Road 1, oil hole 2, camshaft hole 3, water channel hole 4, inlet valve seat 5, delivery valve seat 6, exhaust duct 7, be provided on front side of lid into
Air flue 1 is provided with exhaust duct 7 on rear side of lid, and the both sides of lid are provided with oil hole 2, camshaft hole 3, air intake duct 1, oil duct
Hole 2, exhaust duct 7 are connected to the combustion chamber 8 in lid, and lid upper side is additionally provided with water channel hole 4, inlet valve seat 5, air bleeding valve
Seat 6, inlet valve seat 5,6 interleaved of delivery valve seat are arranged on lid.
The working principle of this specific embodiment: being：Imflammable gas, fuel oil are entered by air intake duct 1, oil hole 2 respectively
Combustion chamber 8 does reciprocating motion of the pistons by pusher cylinder, the camshaft installed in camshaft hole 3 is driven to rotate, pushes
The opening and closing of inlet valve seat 5 and delivery valve seat 6, while combustion chamber 8 is discharged by exhaust duct 7 in exhaust gas, while through water channel
Hole 4 carries out cooling water circulation, to reduce the temperature of complete machine.
Present embodiment shortens the distance between camshaft and valve, while the tappet of valve is omitted and endures
Column simplifies camshaft to the transmission mechanism between valve, the structure of engine is become compacter, reduces assembly difficulty,
So that engine is suitable for running at high speed, the peak value of engine is improved；By rocker arm support direct-drive, use is avoided
Vibration caused by elongated tappet transmission, has been effectively relieved parts depreciation so that the unlatching of valve and closes at long-time service
Design original intention is still followed strictly afterwards, and the whole transmission ratio of camshaft is improved, which not only reduces entirely
The weight of engine, at the same also reduce the monoblock cast of engine, assembly difficulty and engine blank rejection rate and at
This, stability is good, and reliability is high, has a vast market application prospect.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
