Abstract
A volume store which has a substantially hollow cylindrical housing and a separating element displaceably disposed within the housing. The housing is fixedly disposed within a hollow chamber of a camshaft.
Claims11
An assembly comprising:
- a camshaft including an inner surface, the inner surface including a first conical bearing face and a cylindrical circumferential face extending axially from the first conical bearing face;
- a separate component fixed in the camshaft at the cylindrical circumferential face, the separate component including a second conical bearing face, the first conical bearing face, the second conical bearing face and the cylindrical circumferential face defining a cavity inside the camshaft;
- and
- a volume store comprising:
- a cylindrical housing, which is arranged non-displaceably within the cavity of a camshaft, having axial ends each including an opening therein, a first of the axial ends including a first radially inwardly extending region;
- a separating element, which is arranged displaceably within the housing;
- and
- a spring element supported firstly on a side of the separating element facing away from a storage space and secondly on the first radially inwardly extending region of the housing,
- the axial ends of the housing each bearing against one of the conical bearing faces.
