<p>A poppet valve (13) has a valve body (14) and a closure member or valve stem (17) disposed in a bore (23) in the valve body. The interior of the valve body is hollow, and is closed at one end. When the valve is open, fluid passes into the interior of the closure member (17) through apertures (22) and passes along the interior of the closure member. The valve (13) can be located in the cylinder head of a marine propulsion unit to act as a purge port (9) of a post-immersion restart system.</p> |
