Filling valves such as inflatable dinghies are usually self-closing type, that is, so-called one-way valves, and the valve body moves to the open position when compressed air is supplied, and closes when the compressed air supply is stopped. Close the valve immediately. The valve member is typically a diaphragm or plate-like element of flexible material. To release air from the hollow body, push down on a pin attached to the diaphragm to open the valve. It is also known to open the discharge valve by means of an extension of the closing plug of the filling valve (see German Publication No.
2020302).

It is also known to rotatably support a pin coupled to a diaphragm with a valve member (see German Publication No.
2548297, West German Utility Model No. 2716654). In the latter case, the diaphragm comprises a rigid core of resin material with an upwardly projecting extension. Normally, this extension projects beyond the opening in the valve body to allow the diaphragm to engage the valve seat.
Axial displacement of the pin against the spring causes the extension to disengage the opening, thus allowing the diaphragm to rotate about its axis to maintain the valve in the open position. In the last-mentioned embodiment, the pin includes a transverse pin that is axially displaceable within an elongated slot in the valve member. When this pin is displaced sufficiently axially against the spring, the transverse pin can be pivoted and brought under the abutment so as to hold the valve in the open position.

Both examples described above allow the use of ejection pumps to eject the hollow bodies quickly and completely. The valve construction is relatively expensive. Among other things, these require a metal spring to bias the valve member toward its closed position. These springs are typically coil springs, and the springs are particularly susceptible to corrosion if used in conjunction with inflatable dinghy valves. Another disadvantage of known valves is that they require a relatively large number of parts and are difficult to assemble.

The problem is that a dead center spring is connected to the valve member above the valve member, and the spring is fixed to the valve housing around the dead center to hold the valve member in a closed position and an open position above and below the dead center, respectively. It is solved by doing.

The valve member of the valve of the invention is biased to a closed position by a dead center spring. When the valve member is axially displaced to the open position, the dead center spring suddenly crosses the dead center and holds the valve member in the open position under a biasing force. The air from the hollow body can be drawn out gradually and/or by means of a pump. By simply grasping the dead center spring, the spring can be jerked past dead center again so as to bias the valve toward its closed position. Normally, during inflation by a pump with a check valve, the valve member may be closed by the gas or air in the hollow body if the pressure of the gas or air is sufficient. The differential pressure across the valve member is then sufficient to overcome the biasing force of the dead center spring and move the valve member to its closed position.

Therefore, the dead center spring of the filling and releasing valve of the present invention is
It is not only the closing spring for the valve, but also the retaining member that attaches the valve element to the valve housing. Finally, the dead center spring serves to hold the valve member in the open position. Due to the three functions of the dead center spring of the valve according to the invention, it is clear that the valve may consist of a minimum number of parts that are easy to manufacture and assemble.

As already mentioned, a connection between the dead center spring and the valve member is necessary. One embodiment of the invention proposes that the valve member has a journal or tap that cooperates with the dead center spring. This tap may extend beyond the dead center spring to enable manual displacement of the valve member into the closed or open position, respectively.

The dead point spring may, for example, be formed by an arcuate diaphragm, the outer periphery of which is fixed to the valve housing, and the diaphragm's center connected to the valve member. However, according to another embodiment of the invention, the dead center spring is axially fixed to the valve housing and has a retaining ring coupled to the valve member via a flexible arm, the arm being It is preferred that the valve is S-shaped in the closed position. Compared to a diaphragm, the arms have the advantage of exhibiting a pronounced dead center behavior and allowing a large effective cross section for fluid flow.

The dead point spring and the valve member may be integrally formed of resin material, thus significantly reducing the number of parts. Assembly of the integral parts is preferably from above. However, this requires a specially shaped valve plate and remaining parts. Accordingly, another embodiment of the invention provides that the tap is connected to the central receiving part by a releasable bite-type connection, which receiving part is connected to the arm for its role. . The rear dead center spring on one side and the valve member on the other side are therefore two separate parts that can be joined together with a bite-type connection. During assembly, the valve member lies below the dead center spring in the valve housing already fixed to the hollow body, while the dead center spring is inserted from above. The parts are joined into a unit by pressing the parts towards each other.

There are different construction possibilities for forming a bite-type connection between the above-mentioned parts. An embodiment of the invention provides that the receiving part has a ball-shaped seat, the entrance opening thereof has a diameter smaller than the diameter of the seat, and the wall of the opening has at least one resiliently deflectable The tap has a spherical portion which is bitably inserted into the seat. This seat defines a ball-shaped cup which securely accommodates the spherical part of the tap. The taps are thus allowed to make small movements relative to the seat or receiving part or valve housing respectively, which is advantageous for an even engagement of the valve member on the valve seat.

The elastic arms are S-shaped as described above. Preferably, the three elastic arms are arranged equidistantly from each other. According to another embodiment of the invention, the connection of the resilient arm to the valve member and/or the retaining ring is of a hinge-like nature. This hinge-like connection acts in such a way that the essential spring force is generated in compression of the S-arm. Thereby, a progressive displacement force is obtained from the end position in both displacement directions, towards the dead center. Upon reaching the dead center, the resilient arm automatically jerks past the dead center so as to displace the valve member to its other end position.
