Particularly suitable for valves of internal combustion engines, having a valve clearance adjusting element arranged inside the valve cup and cooperating with the valve valve, and an elastic membrane sealing the area filled with an incompressible medium inside the valve cup. The present invention relates to a valve clearance adjustment device.

German Patent Application No. 2517370 discloses, inter alia, a hydraulic valve clearance adjustment device for internal combustion engines. A valve cup of cast material having a generally U-shaped cross section cooperates radially internally with an axially movable piston defining a sealed pressure chamber within the valve cup and cooperates with a camshaft. Let's do it. Inside the pressure chamber there are several parts that constitute the actual valve clearance adjustment element.

In the case of new devices, protrusions of various constructions are envisaged, making it impossible to use membranes adapted in the prior art as sealing means. Furthermore, the cast components are relatively heavy, unnecessarily increasing the overall weight of the unit, which has a particularly negative effect on the price structure.

The basic object of the invention is therefore to provide the possibility of a close contact means of the above-mentioned type to the cup tappet with a sealing system, which is able to adjust the temperature rise and volume changes of the medium and/or the wear of the parts. It's about finding out. At the same time, the contact means must be capable of transmitting the applied rotational moment from the valve cup to the valve. Furthermore, for competitive reasons, there is a need to provide a weight-optimized valve clearance adjustment device.

This object is achieved by providing, according to the invention, that the valve cup consists of a cylindrical component and a circular component, both of which are lockingly connected to each other, in which case the membrane is connected to the cylindrical component of the valve cup and to the valve. This is achieved by extending generally radially between the clearance adjustment elements. The image components of the pulp cup are made of metal plates for weight reasons.

In order to provide a locking connection between the image components, the cylindrical component is provided with a radially inwardly circumferential collar on its camshaft-side portion, and the circular component is provided with a circumferential collar facing radially inwardly on its camshaft side; It has been proposed to provide the area with circumferential folds extending towards the membrane. The circular component can be superimposed and axially snapped onto the cylindrical component.

According to another concept of the invention, the membrane in the region of the folds of the circular component is provided with a sealing thickening that abuts the circular component, especially under axial stress. The membrane is bonded to the cylindrical component of the valve cup by vulcanization or is attached to the internal reference of the cylindrical component, for example by being tightened radially and possibly axially using another reinforcing element. Can be fixed in position. In this case, it is necessary to select the embodiment depending on the application.

Furthermore, according to another concept of the invention, the inner periphery of the membrane that receives the valve clearance adjusting element can be formed with metal reinforcement. In this case, the metal part is preferably of approximately cylindrical design and can be bonded to the membrane by vulcanization. The vulcanized metal part has, in particular at its end facing the pressure chamber, a radially inwardly directed projection which in the assembled state serves as an axial stud for the valve clearance adjusting element. The inner circumferential surface of the membrane facing the valve clearance adjusting element has an axial section extending in the axial direction. The valve clearance adjusting element can thus be fitted axially into the membrane up to the protrusion of the metal part, thus making it possible to dispense with a separate radial protrusion for lateral guidance of the valve clearance adjusting element.

A similar type of sealing is selected at the locking connection between the cylindrical and circular components of the valve cup,
The acceptance of forces acting eccentrically on the bottom (circular component) into the guiding jacket (cylindrical component) is essentially carried out by means of a metal snap connection. The sealing effect against the hydraulic fluid is achieved by pressing and deforming the rubber thickening, in particular at the periphery of the vulcanized membrane, by the folds surrounding the circular structure.
