A valve coupling assembly has a first fluid line connector coupled to a first fluid line and a second fluid line connector coupled to a second fluid line. In an operational state, the first and second fluid line connectors are engaged to each other for fluid communication between the first and second fluid lines. In a disengaged state, the first and second fluid line connectors are disengaged wherein the first and second fluid lines are disconnected. A first valve arranged in the first fluid line connector is configured to control a fluid flow in the first fluid line. In a closed state of the first valve, the first fluid line is sealed, and, in an open state of the first valve, the first fluid line is open. The second fluid line connector comprises at least one push element mounted to a body of the second fluid line connector.

Valve coupling assembly

A vehicle drive having a vacuum system for a vehicle having an internal combustion engine that is connected to a supply air line and to an exhaust air line. The vacuum system has an ejector. A propellant gas line opens into a nozzle channel of a propellant nozzle of the ejector. The nozzle channel opens into a mixing chamber of the ejector through a nozzle opening. A suction line opens into the mixing chamber and the mixing chamber on an outlet side opens directly or indirectly into a mixed gas line. The mixed gas line opens into the supply air line. The suction line is connected to a vacuum consumer, and the nozzle opening in the propellant nozzle is formed by a nozzle edge having teeth and/or corrugations.

Vehicle drive comprising vacuum system and ejector

An angle piece for fluidically connecting fluid lines of a vehicle. The angle piece has a channel portion for altering a flow direction of a fluid about an alteration angle. An input flow direction of the fluid into the angle piece and an outlet flow direction of the fluid from the angle piece form limbs of the alteration angle. At least one guide element is arranged in the channel portion, which guide element protrudes into the channel portion. The at least one guide element altering the flow direction of a part of the fluid by the alteration angle. The angle piece thus has a low pressure drop.

A device for connecting two tubular objects has a connection piece housing and a securing element. The securing element is shaped in a complementary manner with respect to a receiving opening of the connection piece housing and is arranged rotatably in the receiving opening and has an insertion opening for receiving a connection piece. The securing element has securing tabs which are spaced apart from one another in the circumferential direction and each have a radially inwardly facing securing body for engaging in shaped features of a connection piece and can be moved from a first position into a second radial position lying radially on the outside. The connection piece housing has, for each securing tab, a ramp surface which is bevelled radially inwards and on which the securing tab rests.

A jet pump comprising a jet nozzle for accelerating a propellant. The jet nozzle has a convergent inlet part and an outlet part connected to the convergent inlet part. The outlet comprises an inner wall diverging at an opening angle. The opening angle is designed such that a propellant flowing through the outlet part at subsonic speed is detached from the inner wall and a propellant flowing through the outlet part at supersonic speed is guided by the inner wall. An automatic, cost-effective and simple changeover of the jet pump to different pressure ratios is hence provided.

Jet pump

A clamp for fastening an object in the form of a tube or hose, having an elongate clamp strap at each of the ends of which there is provided a radially outwardly projecting fastening leg, and having a rubber profile which is provided on the radial inner face of the clamp strap and which at least partially engages around each of the edges of the clamp strap by way of a lip. At least one first holding geometry is provided on the radial inner face of the clamp strap, and at least one second holding geometry is provided on the radial outer face of the rubber profile.
