Definitions
- the present invention relates to an improvement of a direct-acting hydraulic lash adjuster in which a rush adjuster hydraulic unit is built in a bucket.
- Valve mechanisms in internal combustion engines are generally susceptible to wear and thermal expansion, and the valve spacing changes during operation, adversely affecting output and noise.Therefore, hydraulic lash adjusters that appropriately compensate for this gap are used. Is now available.
- a direct-acting valve train in which the cam directly strikes the shaft end of the valve, for the purpose of reducing the weight of the internal combustion engine equipment, has a hydraulic lash adjuster as shown in Fig. 33.
- This hydraulic lash adjuster is composed of a bucket X and a hydraulic unit Y for hydraulic lash adjuster housed in the bucket, and is interposed between the force 80 and the valve 8 1 shaft end.
- the hydraulic unit Y includes a bottomed cylindrical plunger 50 having an oil hole 51 at the bottom, and is slidably mounted around the outer periphery of the plunger 50.
- a low-pressure cylindrical body 70 forming a chamber S 0, an elastic body S 1 interposed in the high-pressure chamber 60 and biasing the body 70 toward the closed surface side;
- a check ball 62 provided in the chamber 60 for controlling opening and closing of the oil hole 51, a check ball spring 63 for holding the check hole 62, and a check ball It is made up of 6 ⁇ 4 ⁇ .
- the hydraulic unit Y is built in a packet Xp3 ⁇ 4, and a main reservoir 52 for oil reservoir is provided between a back surface of the face disk 90 of the packet X and a hollow portion of the plunger 50, and further a packet.
- the main reservoir 52 separated from the peripheral wall of the plunger 50 is provided with a bar flow relief 5 3
- a sub-chamber 40 is formed through which the hydraulic oil is supplied.
- the hydraulic oil is supplied to the sub-chamber 40 through the oil feed hole 100 of the cylinder head and the oil supply port 20 of the bucket X.
- the cam & 0 comes into contact with the face disk 90 of the bucket X, and the end of the shaft of the valve 81 comes into contact with the closing surface of the body 70, and the cam 80 goes through the hydraulic lash adjuster.
- the valve 8 is directly hitting the shaft end.
- Such a hydraulic lash adjuster further reduces the volume generated in the hydraulic oil itself when the hydraulic oil filled in the high-pressure chamber 60 is pressurized and the elasticity effect due to leak down to the outside, and further reduces the pressure.
- the stiffness effect of the hydraulic oil which is generated when the compression of the added product does not proceed any more, is used together with the following:
- the elastic body 61 inserted into the high-pressure chamber 60 is used. By generating a repulsive force that tends to elongate, it performs a catching operation so that the clearance of the valve operating mechanism generated due to thermal deformation or the like becomes zero.
- Such a conventional direct-acting hydraulic lash adjuster is mounted on a horizontally opposed engine or an inclined engine, and the hydraulic lash adjuster is mounted on the engine. If the adjuster is not in the vertical position, or happens to be tilted in use, the internal and external reservoirs 40, 52 and 2 'operate when the internal combustion engine stops. Oil leaks from the clearance between the body 70 and the sleeve 30 and air enters the space instead.
- the hydraulic lash adjuster in the bottomed state sucks hydraulic oil from the reservoirs 40 and 52 into the high-pressure chamber 60 to compensate for the shortage of hydraulic oil when extending to the predetermined position.
- the air that has entered enters the high-pressure chamber 60 from the main reservoir 52, and the hydraulic oil that should be generated in the high-pressure chamber 60 when the plunger 50 is pressed is released.
- Rigidity is extremely reduced (it becomes a sponge state), making it impossible to correct the valve clearance properly and increasing the seating noise of the valve.
- the bottomed state means that when the internal combustion engine stops while the cam nose 80a presses the face disk 90 of the bucket X, the hydraulic unit Y is compressed as shown in FIG.
- the present invention has been made in view of the above-mentioned problems of the prior art, and a first object of the present invention is to prevent air from entering the reservoir to prevent the air from entering the high pressure chamber when the machine is restarted.
