Ventilhus för salivsug i dentalutrustning
The purpose of this work is to find out if the suctionvalve to the
salivaejector for dental equipment in a simple way can be improved or if a new
design is needed. The result of the examination of the suctionvalve shows that
the friction between the piston and the seal is high and that this causes the
valve in a few cases sheaves. The study concluded that only small changes in
material or detail, improve the component.
