Pressure relief valve
First Claim
1. A pressure relief valve for releasing pressure from a system, comprising:
- a valve housing;
a pressure relief conduit provided on said valve housing for fluid communication with the system, said pressure relief conduit having a conduit interior for receiving the pressure and a valve opening between said valve housing and said conduit interior;
a substantially arcuate valve body pivotally mounted in said valve housing for sealingly engaging said valve opening;
wherein said valve body is capable of pivoting in said valve housing between a first position for closing said conduit interior of said pressure relief conduit and a second position for opening said conduit interior of said pressure relief conduit as said valve body slidably traverses said valve opening and continually seals said valve housing from said conduit interior; and
a bias mechanism carried by said valve housing and operably engaging said valve body for biasing said valve body in said first position, whereby said valve body pivots from said first position to said second position against said bias mechanism and opens said pressure relief conduit responsive to a threshold magnitude of the pressure against said valve body.

Abstract
A pressure relief valve for releasing pressure from a system, which pressure relief valve typically includes a valve housing provided on a pressure relief conduit which receives pressure from the system. A valve opening establishes communication between the valve housing and the pressure relief conduit, and a substantially arcuate valve body is pivotally mounted in the valve housing for sealingly and slidably engaging the valve opening. Accordingly, the valve body is capable of pivoting between a first position to close the pressure relief conduit and a second position to open the pressure relief conduit as the valve body slidably traverses the valve opening. A bias mechanism biases the valve body in the closed position in such a manner that the valve body pivots from the closed position to the open position against the bias mechanism and opens the pressure relief conduit, responsive to a threshold pressure of the pressurized fluid impinging against the valve body in the pressure relief conduit.
