Embodiment Construction

[0028] according to figure 1 , the cylinder head cover 1 (only a part of which is shown) includes a receptacle 2 and at least one fluid channel 3 . In this example, a plurality of fluid channels 3 are provided, specifically three fluid channels 3 , which are respectively indicated by double arrows with dashed lines. The receptacle 2 extends cylindrically or conically with respect to the axial direction 4 . In this example, the receptacle 2 has an axially open end side 5 . Depending on the flow direction of the fluid in the fluid channel 3 , the end-side opening 5 can form an inlet opening or an outlet opening. The fluid channel 3 leads to the receptacle 2 . For example, the fluid channels 3 are separated on the inlet or outlet side and thus each lead radially from themselves towards the receptacle 2 so that they are radially fluidly connected to the receptacle 2 . The respective connection points are axially spaced from each other. The common outlet side or inlet side of ...

Abstract

The present invention relates to a sealing structure (10) used for being arranged at a valve (6) on a cylinder head cover (1). The sealing structure has a plurality of radially effective sealing portions (11) and at least one radially permeable passage portion (12); wherein, the passage portion (12) is axially arranged between two sealing portions (11) which are adjacent axially in each case; the sealing portions (11) and the each passage portion (12) are axially arranged on a sleeve (7) of the valve (6) in the way that the two sealing portions (11) which are adjacent axially in each case are axially arranged at two sides of a control portion (8) of the valve (6), the each passage portion (12) is arranged radially flush with the each control portion (8), therefore, when the valve (6) is arranged on the cylinder head cover (1), the sleeve (7) having the sealing structure (10) is axially inserted into a receptacle (2) formed in the cylinder head cover (1), and the sealing portions (11) extrude and rest on, in a radial sealing way, an inner wall (13) of the receptacle (2) which axially face to the sleeve (7) at two sides of at least one fluid channel (3), the at least one fluid channel (3) is controlled via the each control portion (8) and is formed in the cylinder head cover (1).

Description

technical field [0001] The present invention relates to a sealing structure for a valve mounted on a cylinder head cover. The invention also relates to a kit for constructing such a seal. The invention further relates to a valve for mounting on a cylinder head cover and a cylinder head cover with such a valve. Background technique [0002] DE 60029145 T2 discloses a valve that can be mounted on the cylinder head cover. The valve has a sleeve with a plurality of control parts, with the help of which the fluid passages of the cylinder head can be controlled. The valve is mounted to the cylinder head cover such that the sleeve of the valve protrudes in a leak-proof manner into a receptacle formed in the cylinder head and the fluid passage to the receptacle is controlled. Fluid passages formed in the cylinder head are used, for example, to be driven by control variable valves. [0003] EP 1884629 B1 discloses a cylinder head cover which houses a fluid channel and has a recep...
