Abstract: The invention relates to a coupling device for connecting line devices, preferably quick connector, having a coupling housing comprising a connecting device that can be connected to an end section of a line device or of a second connecting device, and a valve body which can be transferred from a closed position to an open position when the end section of the line device or of the second connecting device is brought together with the coupling housing. The valve body can be actuated by means of a force deflecting device by bringing the end section of the line device or of the second connecting device together with the coupling housing.

Abstract: The invention relates to a valve device, preferably for a line device or connecting device. Said valve device comprises a valve body that can be transferred from an open position to a closed position. Said valve body comprises movable sectored devices having sealing edges or sealing surfaces via which, in a closed position, a sealing contact of the sectored device to adjoining sealing edges or sealing surfaces can be established. The sectored devices can at least be in sections moved away in the radial direction from the centre axis when the valve body is transferred to the open position and release a flow area.

Abstract: The invention relates to a coupling device for the connection of pipes to a retaining device, which has an outer part and an inner part arranged in the outer part. This coupling device is characterised in that the outer part and the inner part can move relative to one another and in the longitudinal direction of the retaining device between a locking position and a release position, wherein at least one wedge surface, arranged sloping with respect to the longitudinal axis of the retaining device, is provided on the outer part, which interacts with at least one complementarily formed wedge surface, which is provided on the inner part.

Abstract: The present invention relates to a stabilization means for a corrugated hose comprising at least one corrugated portion with at least one corrugation which projects relative to the corrugated hose and which extends, at least in certain sections thereof, essentially in the circumferential direction of said corrugated hose, said stabilization means comprising at least one annular segment which, when mounted on said corrugated hose, surrounds the circumference of said corrugated hose adjacent the corrugation. For improving the vibration behaviour of corrugated hoses, in particular of charge air hoses, the present invention is so conceived that a stabilization means is provided, in the case of which the annular segment is a substantially planar structure comprising individual threads or strands that are arranged relative to one another.

Abstract: Device for the removable fastening of a plate-shaped component onto a base with a T-groove open in the direction of the component. The invention consists of a pot-shaped receiving element, a head-bolt, a spring element arranged in the receiving-element and a cross bar arranged at the free end of the shaft of the head-bolt. The cross-bar is insertable in the T-groove and movable against the force of the spring element in the direction of the T-groove floor and engageable behind the shoulders of the T-groove by turning through 90.degree.. In accordance with the invention, the cross-bar has at least one stop interacting with one edge of the aperture of the T-groove in front of the head-bolt shaft end bearing the cross-bar. This stop prevents the continued turning of the head bolt after attainment of the locked position.
