Abstract
The utility model discloses an engine with an integrated type breather. The engine with the integrated type breather comprises a cylinder cover of the engine and a cylinder cover cap. A rocker arm seat which is placed inside the cylinder cover cap is tightly pressed on the cylinder cover through a connecting bolt. The upper end of the connecting bolt is provided with a stepped inner cavity, a one-way conducting piece which can be pushed up when downstream gas of a piston of the engine is breathed out, a pipe-connecting bolt which is arranged above the one-way conducting piece and tightly presses the cylinder cover cap on the cylinder cover, and the pipe-connecting bolt is provided with a gas outlet which is communicated with the inner cavity. The engine enables the breather to be embedded inside the connecting bolt of the fixed rocker arm seat, and the concept of a traditional external breather or the concept of designing and arranging the breather inside a crankcase are removed. The breather is arranged on the cylinder cover cap and not directly connected with the crankcase, mixing oil gas of the crankcase is prevented from directly entering the breather, and the oil pumping probability of the breather and the breathing burden are lowered. The purposes of lowering cost, saving space, reducing the number of parts are achieved.

Background technique
As motor, motor whatever must be designed with resuscitation apparatus, so resuscitation apparatus is also very important as one common of motor.Designed, perhaps very simple, design badly, motor can be regular exhales oil, affects the performance of motor.The Main Function of resuscitation apparatus is to be communicated with engine crankcase and ambient atmosphere, it must be an one-way valve structures, only permitted to give vent to anger, do not allow air-breathing, in engine piston to-and-fro motion process, make to produce certain negative pressure in the engine crankcase, guarantee that each sealing place of motor is oil-tight, reduce the resistance in the motor acting process, reduce power loss.At present in the motor, as shown in Figure 3, cylinder head 1, the general stud 10 that adopts connects between valve mechanism cover 2 and the rocker arm bracket 3, with upper cap nut 9, lower nut 8 is pressed on valve mechanism cover 2 and rocker arm bracket 3 on the cylinder head 1 respectively, and used resuscitation apparatus, be mainly diaphragm one-way valve structures and ball check valve structure, both principles are identical, all adopt a specialized spare part of Position Design that on the crankcase shell of motor, maybe can be communicated with crankcase to load onto, increase thus the fabricating cost of resuscitation apparatus and the component of motor, also increased the volume of motor simultaneously.
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 motor with integrated form resuscitation apparatus that can reduce cost, saving installing space, reduce number of spare parts is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of motor with integrated form resuscitation apparatus, comprise engine cylinder cap, valve mechanism cover, the rocker arm bracket that is positioned at valve mechanism cover is pressed on the cylinder head by connecting stud, the connecting stud upper end has the cascade inner chamber, being provided with in the inner chamber can be by the one-way conduction spare that backs down when the descending gas of engine piston is breathed out, one-way conduction spare top is provided with inner chamber and is connected and the pipe connecting bolt of clamping cylinder housing on cylinder head, and the pipe connecting bolt has the air outlet hole that communicates with inner chamber.
Specifically, the large end of described inner chamber has internal thread, the small end of intracavity bottom has conical seal (contact) face, the pipe connecting bolt penetrates with the large end of inner chamber from the valve mechanism cover outer wall and is threaded and the clamping cylinder housing, one-way conduction spare is arranged in the conical seal (contact) face, and the both sides of connecting stud offer respectively and communicate with inner chamber and the position is lower than the inlet hole of one-way conduction spare.
Preferably, described one-way conduction spare is steel ball.
Can also be that described one-way conduction spare is plunger.
The beneficial effects of the utility model are: the utility model is embedded in resuscitation apparatus in the connecting stud of fixing rocker arm bracket, the design concept of having abandoned traditional external resuscitation apparatus or having arranged resuscitation apparatus in crankcase designs, resuscitation apparatus is arranged on the valve mechanism cover, directly be not connected with crankcase, stoped the crankcase mixed oil and gas directly to enter resuscitation apparatus, reduce the oil machine rate of altering of resuscitation apparatus and the load of exhaling, realized the purpose that reduces cost, saving space, reduces number of spare parts.
