ABSTRACT:
A vacuum metering valve comprises a housing having an inlet and a discharge space from the inlet with a flow passage between the inlet and outlet having a valve seat with a valve member which is mounted in the housing for movement toward and away from the seat. The construction includes mechanical means for adjusting the position of the valve member in relation to the seat and in addition temperature control means are provided for varying the position in reference to the seat in accordance with temperature variations. Temperature variations are produced by suitable means for heating and cooling an auxiliary member which is disposed for example between a mechanical adjustment device and the valve member.
