ABSTRACT:
The moisture detector assembly includes a moisture detector having a probe extending into a housing bore to have fluid flow in contact with the probe and exiting through a housing bore orifice. A pressure regulator is mounted to the housing with its outlet opening to the housing bore. The regulator includes a cap closing the regulator bore opposite the outlet to provide a main chamber and has an inlet and a piston extending within the regulator bore to control fluid flow from the inlet to the outlet. The regulator outlet is an orifice for limiting fluid flow from the regulator bore to the housing bore. The piston enlarged head and the opening of outlet toward the head provides a control chamber in the regulator bore with the pressure therein controlling the movement of the piston between fluid flow blocking and fluid flowing positions.
