Problems solved by technology

Since the opening pressure of the one-way valve is small (only a few mbar), the vibration of the engine will cause the spring to vibrate, so that the opening and closing of the plunger valve is irregular, so that the opening and closing state of the one-way valve is not stable. stable, affecting the normal operation of the engine

Embodiment Construction

[0026] Below by embodiment and accompanying drawing thereof, the present invention is described in further detail:

[0027] see figure 1 one image 3 : The one-way valve includes a valve cover 1, a valve seat 2, a circular valve plate 3, the valve cover 1 and the valve seat 2 are sealed and connected and a valve cavity 4 is formed between the valve cover 1 and the valve seat 2, the valve seat 2, the valve cavity 4. The bonnets 1 are connected sequentially, and the valve plate 3 is placed in the valve cavity 4 , and the valve cavity 4 is also provided with a circular blocking plate 5 which acts as a barrier to the valve plate 3 .

[0028] The valve seat 2 is a cylindrical body with openings at both ends. There are six first spokes 21 and a first hub 22 on the side close to the valve cover 1. The first spokes 21 are evenly distributed on the inner wall of the valve seat 2 in the circumferential direction and close The end faces of the valve cover 1 share a common plane, and th...

Abstract

The invention discloses a forced ventilation one-way valve for an automotive engine, of which the structure is that: a valve cap and a valve seat are connected in a sealing mode and a valve cavity is formed between the valve cap and the valve seat; one side of the valve seat close to the valve cap is provided with a first spoke and a first hub, and one side of the valve cap close to the valve seat is provided with a second spoke and a second hub; a concave pit is formed at the outer end of the second hub; a valve block and a stopper are arranged in the valve cavity; a first mounting hole and a ventilation hole are formed on the stopper; two anti-rotation posts are arranged on one side face of the stopper; the valve block is made of an elastic material and a second mounting hole is formed on the valve block; the first hub is inserted into the first mounting hole, and the two anti-rotation posts are spanned on two sides of the width direction of any first spoke., so that the stopper is adhered to the end face of the first spoke close to the valve cap; the valve block penetrates the first hub through the second mounting hole and then is adhered to the stopper and shields the stopper, so the valve cavity is divided into two cavities; the first hub is inserted into the concave pit; and the external end of the second hub is contacted with a central region of the valve block. The forced ventilation one-way valve for the automotive engine cannot be influenced by vibration of the engine, and the opening / closing state of the one-way valve is stable.

Description

technical field [0001] The invention relates to a one-way valve for forced ventilation of an automobile engine. Background technique [0002] The automobile engine includes an intake manifold, a cylinder cover, a cylinder block, and an oil pan. The intake manifold is connected with an air intake system, and the cylinder cover is connected with a ventilation system. [0003] The air intake system includes a throttle valve, a supercharger, an air filter, and an intake hose connected to the intake manifold at one end. The throttle valve, supercharger, and air filter are sequentially arranged in the intake hose and The throttle valve is close to the intake manifold, and the other end of the intake hose is connected to the atmosphere. [0004] The ventilation system includes an exhaust hose connected to the cylinder cover at one end, an oil-gas separator and a forced ventilation check valve arranged in the exhaust hose, and the other end of the exhaust hose is connected with the...
