Abstract
A contamination-free pyrovalve having first tubing section and a second tubing section. The first and second tubing sections are disposed in spaced-apart relation such that a conveying path between the first and second tubing section is established. An opening is disposed between the first and second tubing sections. A valve body is fixedly attached to the first and second tubing sections. The valve body has a bore. A ram is disposed inside the bore of the valve body. A slug is disposed in the opening between the first tubing section and the second tubing section. The slug is held in position by a frictional fit. A combustion chamber is disposed in operative relation to the ram such that when an explosive material is ignited the pressure inside the chamber causes the ram to move through the bore to strike the slug and to displace it from the opening between the first and second tubing sections such that the valve is opened.
