Abstract: A quick connect coupling for transmitting fluids includes a tubular housing and spreadable locking elements fixed on the housing for connection to a correspondingly formed connector. A sealing piston is slidable centrally in the housing for engagement with the connector and surrounded by an axially movable sliding sleeve. The sliding sleeve retains the locking elements in the locking position in the coupled position of the quick connect coupling.

Abstract: A connection adapter designed for gas bottle valves has a clamp-like locking device. An actuating device moves a piston guide bushing axially relative to the locking device to move the bushing into a sealed position in which the bushing bears upon a complimentary shaped connecting element. The actuating device has a threaded sleeve inside which the piston guide bushing is centrally extended, the threaded sleeve and bushing being mounted so that rotation of the threaded sleeve moves the bushing axially without rotating the bushing. A non-rotating, sliding block may be interposed between an end of the bushing and the clamp mounting.

Abstract: The invention relates to a clamping device, in particular for a male coupling, with a substantially cylindrical housing, a clamping member mounted to be axially displaceable therein, and an actuation member which is arranged on the rear end of the housing, linked to the clamping member for axial displacement, pressurized by a compression spring and can be actuated by a hand lever. To increase the axial clamping force while operational force and production costs are kept low, it is provided that the actuation member has a holding bolt arranged centrally on the rear of the housing. A radially expanded stop flange for supporting the compression spring is provided on that end of the holding bolt which is inside the housing, and the hand lever is pivotably mounted on that end of the holding bolt which is outside the housing.

Abstract: A clamping jaw arrangement for a clamp system includes several clamping jaws and a fitting arrangement.

The fitting arrangement is configured for the spreader mandrel and formed as a star-shaped fitting, which is mounted in the casing in a peripheral area of the clamping jaws and at an inner end of the spreader mandrel. The fitting includes at least three spokes, which are radially aligned between two respective clamping jaws.

Abstract: A rapid connection coupling for transferring gaseous and/or liquid fluids includes a tubular housing, an outer sliding sleeve and a plurality of locking elements. The outer sliding sleeve is slidably mounted relative to the housing and the locking elements are attached to the housing and movable radially. The locking elements have an engagement profile for connection to a correspondingly formed connection nipple. A sealing piston is centrally slidable in the housing for engagement on the connection nipple, and a spring-biased ring piston is axially displaceable in the housing. The spring piston holds the sealing piston in a retracted position and is displaceably seated relative to the sealing piston.

Abstract: The invention relates to a collet device, in particular for snap closure attachments for gaseous and/or liquid media which comprises a clamping plunger and a plurality of collets each with a connection end and a bearing end. The bearing ends of the collets are detachably suspended on the clamping plunger and the collets can be displaced axially with the clamping plunger using an actuating member. For simple and rapid replacement and assembly of the collets the invention proposes that the collet arrangement is linked to a fixing member movable in relation to the collet arrangement in order to block the bearing ends positively.

Abstract: In order to provide a simple and reliably operating filling apparatus, particularly for pin-index gas bottle valves there is proposed a housing, a through opening formed in the housing for displaceable reception of a corresponding gas bottle valve, a filling union section fixed to the housing and opening into the through opening by way of a sealing neck, and a displacement member by means of which the sealing neck can be connected to a gas bottle valve located in the through opening.

Abstract: A quick-connect fitting for transferring gaseous and/or liquid media, in particular for filling gas cylinders, has a housing (11) with an inlet (12), and outlet (13) for the medium to be transferred and a quick-connect device arranged in the area of the outlet (13) with clamping tongs (15, 15') that can be interlocked with an external complementary gripping profile, a hollow sealing piston (16, 16') that can glide in the housing (11) and an actuating device (17) for applying the clamping tongs (15, 15') which is linked to the sealing piston (16, 16') in a relatively movable manner by means of a sliding sleeve (18, 18').At least one bolt (20) is provided for linking the sliding sleeve (18, 18') to the sealing piston (16, 16') and the actuating device has an elongated member (17) mounted on the housing (11) with a disk cam (36) that engages the sliding sleeve (18, 18') to make it move.

Abstract: A plug coupling for providing a pressure-sealed connection to a device having a cylindrical connector. The coupling has a tube-like support element having a front portion provided with a sealing ring and a rear portion formed as an inlet part. Elongated clamping jaws are linked to the support element and extend in a generally axial direction. The clamping jaws are arranged concentrically around a longitudinal axis of the support element and have free ends radially displaceable. A sleeve surrounds the support element and is shiftable in longitudinal direction and has a front end portion provided with a rim for engaging peripheral surfaces of the clamping jaws for locking them in an engaged position. The sleeve is urged into the engaged position either by a spring or by pressure. An arresting device blocks the sleeve to prevent this engagement of the plug coupling when fluid pressure is applied thereto.

Abstract: For a simple operation and high safety in a coupling for fluids under pressure, an arrangement of an inlet valve, a ventilation valve and an outlet valve in the coupling housing is proposed, the inlet valve, and ventilation valve being brought alternately into the open position by an operating device, e.g., an eccentric shaft. Due to this alternate blocking of the valves, at least one valve is always closed even on faulty handling, so that fluid under pressure cannot escape. This coupling is thus suitable especially for high pressure filling at filling stations, since high safety and simple operation are achieved. A simplified coupling is described, which can be operated by hand, enabling fast coupling and disconnection, so that fluid cannot flow out.

Abstract: A plug coupling for providing a pressure-sealed connection to a device provided with a connecting member comprising a cylindrical housing; a piston shiftable within the housing clamping jaws connected to the piston and concentrially arranged around the longitudinal axis of the housing and radially displaceable by means of a ramp arrangement by an axial movement of the piston relative to the housing; pressure is applied to said piston for moving it in longitudinal direction of the housing thereby pressing the clamping jaws radially inwards or outwards by means of said ramp arrangement. The free ends of the clamping jaws are moved into an engaging position for engagement with said connecting member.

Abstract: The coupling is provided with a cylinder (15, 49) within which a piston can be moved under pressure in one direction or the other. The piston has attached to it a clamping device in the form of jaws (32) which are adapted to be pressed together radially inwards and which are adapted to be fixed in a spread-apart position. The outer circumferential surface (41, 42) of the cylinder has provided on it a sleeve (4) which is adapted to be displaced and which is capable of occupying several positions, the jaws being pressed together in one of said positions and the jaws being spread apart in another position, and in a third position pressurized air can be applied to a connection.
