Abstract
The utility model relates to a ventilation structure of an engine, in particular to the ventilation structure of the engine inside a cylinder cover mask covered above a cylinder cover. The utility model is characterized in that a first baffle and a second baffle dividing a ventilation chamber into three cavities are connected with each other in the cylinder cover mask; a respiratory shrapnel and a pressure plate of the respiratory shrapnel with a check structure are arranged at the entrance of the ventilation chamber and connected with a bottom plate. The ventilation structure of the engine has a simple, compact and reasonable structure; as the three cavities are formed in the ventilation chamber, the passing path of the oil gas can be ensured and the removal effect of oil mist is facilitated; besides, the property decreasing of the engine and the increasing of the gas exhaust caused by the inlet gas sucks the oil gas with overhigh oil content can be restrained; the oil consumption of the engine can be reduced.
Description
Technical field
The utility model relates to a kind of ventilation device of motor, specifically covers the air-breather of the motor in the valve mechanism cover of cylinder head top.
Background technique
In prior art, the ventilation device of motor all is to form by valve mechanism cover madial wall and base plate and the outstanding floor that is provided with of base plate, the path that oil gas is passed through is shorter, and Oil-gas Separation is insufficient, and the inlet of suction oil gas directly sucks ventilation chamber by a valve opening, make in the oil gas oil content many, can't fully separate after entering ventilation chamber, a part of oil gas directly feeds in the air inlet, has sucked the too much mist of oil of oil content in the air inlet, cause engine performance to descend, exhaust emissions increases.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of ventilation device of motor, can suppress to suck the increase that the too high oil gas of oil content causes engine performance decline, exhaust emissions in the air inlet, and can reduce the oil consumption of motor.
Main solution of the present utility model is achieved in that
The utility model mainly adopts in the valve mechanism cover above the cylinder head of motor ventilation chamber is set, feature is to connect first baffle plate and second baffle in valve mechanism cover, first baffle plate and second baffle are cut apart three chambeies of formation with ventilation chamber, can guarantee the path length that passes through of oil gas, be used for separating and removing the mist of oil of oil gas.The breathing shell fragment of formation one-way valve structures is installed in the ventilation chamber ingress and is breathed the sheet pressing plate, breathing shell fragment and breathing sheet pressing plate are installed and are connected on the base plate.
The described retaining mist of oil structure that is provided with in the ventilation chamber ingress.
Describedly be provided with the draining hole in the minimum position of ventilation chamber.The described position that is lower than empty filter inlet hole in the valve mechanism cover side is provided with air outlet hole.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to form three chambeies in vent chamber, can guarantee the path length that passes through of oil gas, and can improve the removal effect of mist of oil; Retaining mist of oil structure is set in the ventilation chamber ingress, before oil gas enters ventilation chamber inside, with the part mist of oil attached on the oil baffle structure and be removed, can prevent that too much mist of oil from entering ventilation chamber, the air outlet hole that is lower than empty filter inlet hole is set in the ventilation chamber outlet port, separate once more when helping mist of oil, prevent that mist of oil from can't effectively separate and directly suck in the intake duct in vent chamber by breathing pipe; Suck the too high oil gas of oil content in the air inlet quickly and can cause engine performance to descend, exhaust emissions increases; Be provided with the draining hole in the minimum position of ventilation chamber in addition, the oil that vent chamber can be separated flows back to motor naturally, can reduce the oil consumption of motor.

Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model is made up of cylinder head 1, valve mechanism cover 2, ventilation chamber 3 (3a chamber, 3b chamber and 3c chamber), breathing shell fragment 4, breathing sheet pressing plate 5, base plate 6, first baffle plate 7, second baffle 8, retaining mist of oil structure 9, draining hole 10, air outlet hole 11, breathing pipe 12 and the empty filter inlet hole 13 etc. of motor.
As Fig. 1～shown in Figure 4: valve mechanism cover 2 is installed above the cylinder head 1 of motor, in the inner ventilation chamber 3 that form of valve mechanism cover 2, this ventilation chamber 3 is breathed one-way valve structures that sheet 4 and the base plate 6 of breathing sheet pressing plate 5 form and valve mechanism cover 2 inner side surfaces and is centered on and form with breathing sheet pressing plate 5 and install by breathing sheet 4.In valve mechanism cover 2, connect first baffle plate 7 and ventilation chamber 3 is cut apart formation 3a chamber, 3b chamber and 3c chamber, can guarantee the path length that passes through of oil gas, be used for separating and removing the mist of oil of oil gas with second baffle 8, the first baffle plates 7 and second baffle 8.
Secondly, form the ingress base plate 6 arranged outside oil baffle structures 9 of one-way valves in this ventilation chamber 3, before oil gas enters ventilation chamber 3 inside, with the part mist of oil attached on the oil baffle structure 9 and be removed, can prevent that too much mist of oil from entering ventilation chamber 3, guarantee that oil gas can effectively separate in the ventilation chamber 3.
Simultaneously in ventilation chamber 3 inside, the lowest part of valve mechanism cover 2 mounting points is provided with draining hole 10, isolated machine oil in ventilation chamber 3, naturally flow back to motor by valve mechanism cover 2 draining hole 10 bottom, lead to empty filter inlet hole 13 after the air outlet hole 11 that is lower than empty filter inlet hole 13 that gas is provided with by valve mechanism cover 2 sides separates once more through breathing pipe 12, enter engine inlets.
As mentioned above, motor ventilation device of the present invention is the ventilation device that can more effectively remove oil component in the mist of oil.
