ABSTRACT:
A blocking-type valve for isolating or closing a fluid path comprises a housing body forming a throughgoing fluid passage and, at an intermediate location along this passage, a valve seat inclined to the general direction in which the passage extends. A valve-closure member is axially shiftable into engagement with the seat and is provided on a sliding rod. The valve body also contains a tubular member or sleeve concentric with the end of the rod carrying the valve-closure member and of a length and cross section such that, in the open position of the valve, the interior of this sleeve is sealed off by the closure member.
