Abstract
A quick release valve including a housing, a high pressure fluid inlet in the housing, a fluid outlet in the housing, a first plunger having a valve member at a first end thereof, a second annular plunger axially aligned with the first plunger and having a seat on the end thereof for receiving the valve member, a toggle linkage mounted between the housing and the second end of the first plunger for maintaining the valve member on the seat when the toggle linkage is overcenter but permitting the valve member to pull away from the seat when the toggle linkage is broken, and a lever with a weight thereon attached to the toggle linkage for biasing the toggle linkage to a broken condition but which is ineffective for doing so when the toggle linkage is in an overcenter position as a result of fluid pressure being exerted on the valve member.
