20140158924 | VACUUM VALVE AND CLOSURE MEMBER FOR CLOSING A FLOW PATH IN A GAS-TIGHT MANNER BY MEANS OF A LINEAR MOVEMENT - A vacuum valve closes a flow path in a gas-tight manner using a linear movement and includes a closure member, a first sealing surface of the valve housing that encloses the opening, and a corresponding second sealing surface of the closure member. In the closed position, the second sealing surface is in sealing contact with the first sealing surface. In the region between the opening and the first sealing surface, the valve housing includes a first sloped surface that encloses the opening, and the closure member includes a corresponding, parallel second sloped surface. The sloped surfaces, which have a sloping angle between 3 and 15 degrees relative to the geometric adjustment axis, are located such that, in the closed position of the closure member, the second sloped surface is arranged in a parallel position opposite the first sloped surface at a distance of 0 and 0.6 mm. | 06-12-2014 |
20140183391 | VACUUM SLIDE GATE VALVE - A vacuum slide gate valve with a drive unit that is formed in such a way that a closure plate, by displacement of at least one valve rod along a longitudinal axis, is displaceable from an open position into an intermediate position, and, by displacement of said valve rod along a transverse axis running at right angles to the longitudinal axis, is displaceable from the intermediate position into a closing position. The valve rod is rigidly connected to a sliding part, which is guided between a first position and a second position parallel to the longitudinal axis, and between the second position and a third position parallel to the transverse axis. A displacement member is mechanically coupled to the sliding part via an inclined connection to displace the sliding part from the first position into the second position and from the second position into the third position. | 07-03-2014 |
