Description

[Detailed description of the invention] media dispenser This invention provides a disc for gases, liquids, pastes, powders and other flowable media. Regarding Pensa.

According to this invention, it is possible to have a pressure chamber. This pressure chamber is is connected to a discharge opening, for example a nozzle. and/or to at least one valve. can also be connected for highly reliable operation control. With such a valve These include inlet valves, outlet valves or other valves.

The object of the invention is to overcome the disadvantages of the known constructions and to achieve particularly high positional stability or specificity. The aim is to achieve very reliable closure with the valve.

This problem is solved as follows. i.e. at least one valve is locked or at least one position, especially the closed position, by at least one constraint in a similar manner Fixed to.

This allows it to be immovable in the open position or locked in the closed position to keep it in place. enable the restraint to be released by application of a disengagement force, causing it to occur It can be made to pass to another position.

Preferably, such a lock is formed directly by contact between the valve body and the valve seat. do. Valve body symmetrically around the axis for accurate and simple determination of locking force It is closed by applying a preload to the passage that forms the valve seat in the jacket. It can be inserted as a standard component.

Restraints or locks can also be created by fluids. Two valves are activated by changes in fluid pressure. Move between positions. This will be in the form of fluid suspension or damping. . For example, a pressure chamber can be compressed when the position of the valve body changes. This is For example, formed by a gas or air light line hole connected to the valve seat. Ru. The restraining force can be adjusted by changing the volume of the pressure chamber in relation to the two valve positions. is possible. The restoring spring is made up of fluid pressure, reducing the need for valves. Both can be restored to one position, especially the closed position.

In particular, single-use dispensers and/or one-way dispensers configuring to deliver almost the entire volume of storage medium in one complete pumping stroke. For complete evacuation, the valve should be installed in the media chamber or near the outlet passage as an outlet valve. A reliable sealing structure for the pump chamber can be formed. Under the pumping pressure moving the open structure to the open position where it can be stuffed, locked, or stopped. Attach it by engaging it. The structure of the valve is DE-○5353289 0 dispensers are preferred. Please refer to this content for detailed structure and operation. with reference to the contents of this specification.

In particular, if the dispenser is configured according to patent application P3909031.0 , a moving member or valve body mechanically connected to the pump cylinder by another member. It is desirable to compose the body. This component is made of a different material than the cylinder. and is connected thereto by a fixed connection member. Therefore, the cylinder is a very simple container made of glass or a material with similar properties. can be formed with. Such cylinders are often used as valves or moving parts. Not elastic. A more elastic moving member is combined with a more rigid glass container. It is also possible to configure closed standard components.
