Problems solved by technology
Prior art for filling / emptying air-conditioning systems, in particular in the automotive industry (the air-conditioning systems use CO 2 as a connection adapter solution for coolant) is based on existing solutions for other coolants and cannot provide high tightness requirements with a long service life / operating cycle
[0003] Especially when the CO 2 When used as a coolant, solutions to date have not been able to provide the durability of the sealing system at the same time as high tightness in operation under pressure

Embodiment Construction
[0017] The connection adapter 11 according to the invention has a housing 3 which includes a pressure space 12 . The pressure space 12 is substantially formed as a central recess or bore extending along the valve axis 13 , in which the switching valve 4 is arranged displaceably along the valve axis 13 . The feed line 14 opens transversely to the valve axis into the pressure space 12 . A connecting unit 15 is provided on the supply line, via which the connection adapter 11 is connected, for example via a line, to a maintenance appliance or a reservoir for coolant. exist figure 1 A first fluid system 37 is schematically shown in , with which an input line or connection unit is connected.
[0018] The switching valve 4 has a closing part 7 on one side, which is in the closed position of the switching valve 4 ( figure 1 and 2 ) seals the pressure space 12 on the conical valve surface 16 . On the side of the pressure space 12 axially opposite the valve surface 16 , the press...

The invention relates to a connection adapter (1) for producing a detachable fluid connection between a first fluid system (37) and a second fluid system (38). The connection adapter (1) has a switching valve (4), which is actuable by means of an actuation element (5) for the purposes of selectively opening up and closing off a fluidic connection between a pressure chamber (12) provided in the connection adapter (1) and a valve chamber (31) provided in the connection adapter (1). From the valve chamber (31), a ventilation path leads out of the connection adapter (1), which ventilation path canbe closed off and opened by a ventilation shut-off means (2). A fluidic connection from the pressure chamber (12) to the first fluid system (37) can be produced by means of a connection element (15).The valve chamber (31) is fluidically connected to a quick fastener socket (23) for the connection of a connection element (35) of the second fluid system (38), and the connection adapter (1) has a locking mechanism (39) for the quick fastener socket (23). The locking mechanism (39) is restricted to a locked position when the ventilation shut-off means (2) closes off the ventilation path.
Description
technical field [0001] The invention relates to a device for establishing a detachable fluid connection between a first fluid system and a second fluid system, in particular for establishing a detachable fluid connection between a fluid system of an air-conditioning device and a fluid system of an air-conditioning maintenance appliance. A disconnected fluidically connected connection adapter having a switching valve that can be actuated via an actuating element in order to selectively release and close the pressure space provided in the housing of the connection adapter and the pressure space provided in the housing A fluid connection between the valve spaces, from which a ventilation path leads from the connection adapter, which can be closed and opened by means of a ventilation lock, wherein a connection from the pressure space to the first fluid can be established via the connection unit A fluid connection of the system, wherein the valve space is fluidly connected to a qui...
