Abstract:
1. A pressure relief latch mechanism comprising: a housing; a bolt coupled to the housing for pivotal movement between a first position and a second position, the bolt includes a pair of spaced apart detents on spaced apart sides of the bolt and a corresponding groove communicating with and extending along a portion of the bolt between each of the pair of spaced apart detents; a detention assembly configured to be positioned within the housing and including a pair of spaced apart detent balls, a ball support associated with each detent ball for supporting the corresponding detent ball, a detent spring and an expansion spacer associated with each detent ball wherein the expansion spacer has a coefficient of thermal expansion that differs from that of the housing in order to allow for compensation in the spring rate of the detent spring at different temperatures; wherein each detent ball is configured to selectively engage the corresponding pair of detents when the bolt is in the closed position and roll along the corresponding groove between the corresponding detents when the bolt is moved between the closed position and an open position.
