Abstract

The invention relates to a receiving coupling element, in particular for a connection coupling, for connecting a fluid supply line to a connection piece (9). The receiving coupling element comprises a fluid inlet, a fluid outlet (18) for connecting the receiving coupling element to the connection piece (9), a fluid channel (70) which connects the fluid inlet to the fluid outlet (18), a coupling device for locking the fluid outlet (18) to the connection piece (9), and an outlet valve (50), which is biased into a closed position, for interrupting a fluid flow through the fluid channel (70). The outlet valve (50) can be moved from the closed position into an open position by the fluid outlet (18) being placed onto the connection piece (9), wherein the coupling device has a sliding element (34) which can be shifted along a placement direction between a locking position locking the connection piece (9) and a release position releasing the connection piece (9). According to the invention, the coupling device also has a pressure-controlled safety device (60, 61, 63, 64) which is fluidically connected to the fluid channel (70) and is designed to block a movement of the outlet valve (50) from the closed position into the open position if the pressure in the fluid channel (70) upstream of the outlet valve (50) is higher than a first reference pressure. Thus it is easily ensured that the outlet valve remains closed as long as the pressure upstream of the outlet valve has not yet been reduced. The operating safety of the receiving coupling element is thereby increased.

Abstract

The invention relates to a connection coupling for discharging a fluid into a tank, comprising a housing, a first fluid connection that can be connected to a fluid supply line, a second fluid connection that can be connected to a connection piece of the tank, a channel leading through the housing for conducting the fluid from the first fluid connection to the second fluid connection, a main valve provided in the channel, a coupling device for establishing and releasing a connection between the connection coupling and the connection piece, and an actuating device for actuating the coupling device and the main valve. According to the invention, the actuating device has a handle element which at least partly surrounds an outer portion of the housing and is designed such that the handle element, together with the outer portion of the housing, can be grasped by a user's hand. The handle element is rotatable relative to the outer portion of the housing about an axis of rotation and is coupled to the coupling device and the main valve such that a rotation of the handle element causes an actuation of the coupling device and the main valve. The design of the handle element facilitates a refueling process which is intuitive, user-friendly and safe.

Abstract

The invention relates to a nozzle, which has a main valve arranged in a channel, a coupling device (30) for producing a connection between the nozzle and the connecting piece (15), and an actuating apparatus (17) for actuating the coupling device and the main valve. The actuating apparatus comprises a manual lever (11), which is movable between a closed position and an open position. The actuating apparatus is designed to convert a movement of the manual lever in a region between the closed position and the open position to a temporally offset actuation of the coupling device and of the main valve. A coupling joint (20) connected to the manual lever is connected via operative connections to the coupling device having the main valve. The operative connections for the coupling joint form a guide such that the coupling joint is caused to rotate about a first pivot axis (41) and/or to move in a first direction when the manual lever is activated in a first manual lever region, and that the coupling joint having the manual lever in a second manual lever region is caused to rotate about a second pivot axis (42) and/or to move in a second direction.
