Gasregulierungs-Schaltventil.

摘要

A selector valve for use with a hospital vacuum or positive pressure module to supply vacuum or pressure to a utilisation means. The selector valve has two or more positions and includes a positive stop at each of its positions through the use of moulded plastic parts that interact together to eliminate springs or other components that are tedious to assemble. The entire selector valve is comprised of a minimum of parts and costly lapped surfaces are eliminated by moulding a gasket material to one of the components of the valve. The overall multi-position selector valve is thus inexpensive to manufacture by utilising a minimal number of plastic moulded parts and that are easy to assemble.
