Abstract
A pressure dome is provided with resilient tongues that engage projections on a transducer in such manner as to draw the dome and transducer together when one is rotated with respect to the other. Detent notches for the projection ensure that the force between a dome and the transducer is always the same.
Claims2
A pressure dome for attachment to a transducer having outwardly extending projections, comprising
- a body having a hollow formed therein,
- a flexible membrane,
- means mounting said membrane across said hollow so as to form a space therebetween,
- ports extending through said body so as to provide access to said hollow from a point outside said body, and
- resilient tongues extending from said body on the side opposite said membrane from said hollow, said tongues lying within a cylinder having an axis perpendicular to said membrane and having ramps sloping toward said membrane from their ends and
- means defining detent notches next to said ramps.
