CS229387B1 - Push-button valve for filling glasses in atometological instruments - Google Patents

Abstract

The push-button valve is designed for opening and closing the supply of warm water needed for rinsing the dental cavity from the dental treatment to the cup. The essence of the push-button valve is a housing with a side opening drawn in the body of the fountain by internal drawing books. The housing is equipped with a spray and a button, while this button is drawn in the housing by internal drawing books and a spring, which ensures the reciprocating movement of the button equipped with a recessed β-ring. In addition to the use of dental devices, the push-button valve can be used for dosing water or other flowing media.

Description

The invention relates to a push-button valve which simplifies the opening and closing of the hot water supply needed to rinse the oral cavity from the dental unit into the cup.

Previously known cup filling valves for dental apparatus are electromagnetic or mechanical and are located on the side of the dental apparatus. The water supply is routed from the valve to the fountain under which the bowl and the cup are located. The valves designed on these principles must have a toggle button to reduce the pressure required to open the water supply. Due to the large number of components, the valves are demanding in terms of manufacturing effort, qualification of assembly and service personnel.

The described disadvantages are overcome by the push-button valve according to the invention, which is based on a housing with a lateral opening sealed in the fountain body by external sealing rings. The housing is provided with a shower and a button, the button being sealed in the housing by internal sealing rings and a spring that ensures the reciprocating movement of the recessed button and locking ring.

The advantages of the valve according to the invention placed directly on the fountain are simple construction and easy assembly. Users will benefit from improved ergonomics of the dentist, who controls the flow of water needed to fill the glass at very short intervals with a slight pressure on the button.

The accompanying drawing shows, in cross-section, a button valve positioned on the fountain body.

The cup filling valve according to the invention is formed by a housing 1 into which a push-button 4 is inserted.

A spring 9 is provided with a spring 11 which ensures its return to the original position and at the other end with a fuse 7 which prevents a possible pulling out of the housing 1. The recess 9 on the button 4 has a water supply from the fountain body In the lower part of the housing 1, a removable spray δε is connected through the openings ^ 1, the inner face of which also forms a stop when the button 4 is pressed.

The stream of water enters through the body fountain and the opening W in the housing 1 into the space formed by the groove. After pressing the button 4, water enters the openings 11 in the spike 8 into the glass. By releasing the pressure, the button £ returns to the drain position, closing the water flow ·

The invention can be used with advantages in dental instruments, but also where water needs to be dispensed, other flowing media may be involved.
