    摘要: A hydraulic device in an internal combustion engine for adjusting a rotation angle of a camshaft in relation to a crankshaft includes a tubular stator and a rotor connected in fixed rotative engagement with the camshaft and having plural vanes in spaced apart relationship to define pressure chambers on both sides of the vanes. The stator is connected in fixed rotative engagement with a crankshaft-drive timing pulley and constructed to define with the rotor vanes the pressure chambers. The stator is made by a shaping process without material to effect a mass reduction. Pressure medium is supplied to or purged from the pressure chambers to selectively adjust the position of the rotor in relation to the stator and thereby the position of the camshaft in relation to the crankshaft.

    摘要: A device for continuously adjusting an angular orientation of a camshaft relative to a crankshaft of an internal combustion engine, includes a housing, an adjusting piston dividing the housing into two pressure compartments and reciprocating in the housing between two end positions in response to operation of a pressure fluid circuit, and a sliding sleeve connected in one piece to the adjusting piston. The sliding sleeve has a first toothed section in mesh with a drive wheel that is in driving relationship with the crankshaft, and a second toothed section in engagement with a toothed bushing that is securely fixed to the camshaft. The toothed sections are formed as helical gears so that an axial displacement of the adjusting piston effects a relative rotation between the drive wheel and the camshaft. In one end position, which represents a starting phase, with the internal combustion engine being at a standstill, the adjusting piston is subjected to a retention force so as to be securely held in place whereby the retention force can be overcome during the starting phase only after buildup of a sufficient pressure in the respective pressure compartment.

    摘要: A profiled cage characterized in that, between crossbars (5) in peripheral direction, side rings (1, 2) comprise a slot (15) which is spaced from the ends of the pockets (6) so that a section of material (16) is formed which is retained by two adjacent crossbars (5) and which, in a radially inwards bent state, constitutes the convexity (13, 14) providing an improved contact between the end faces of the rolling elements (7) and the convexities (13, 14).
