Abstract

The shut-off valve drive comprises two pistons (5, 7) separated from each other to run in opposite directions. The separting shaft (2) is so arranged in the cylinder housing (1) that it cuts the housing axis. The shaft (2) has two opposed lever arms (3) which are coupled to the pistons via intermediate links (4, 6). A second cylinder housing (11) with a third piston (18) is installed at one end of first cylinder housing on the same axis. The piston surface facing the shaft (2) can be operated upon by a pressure medium, while the opposite surface is operated upon by a pressure spring (23). The piston rod (12) extends within the bordering section of the first cylinder housing (1).
