Abstract: A spacer for maintaining a gap between a slit valve door and a sealing surface of a slit valve body, such as a metallic insert is described. The spacer can extend the life of a seal by limiting the line of sight exposure of the seal to corrosive gases within a wafer processing chamber, for example, and by controlling the compression percentage of the seal. The spacer may be located on an outer ambient side of the slit valve away from any corrosive gasses that may exist in the chamber. The spacer may be attached to the slit valve door partially in a depression therein, and may be integral with the seal. Further, the present invention provides improvements to a standard slit valve assembly that enhance the effectiveness of the slit valve and the spacer. These improvements include a barrier material to protect the seal, a labyrinth to reduce particle energy, a skew-plane slit valve door, and a recess with sidewalls to continue the geometry of the process chamber in order to move the collision plane away from the seal plane.

Abstract: In a solar generator, comprising a reflector and an electrohydraulic sun-position tracking device with at least one hydraulic cylinder and a hydraulic control seat valve, the reflector can be guided via the control seat valve to follow in synchronism with the course of the sun continuously and uninterruptedly. The control seat valve for regulating a pressure medium flow permanently supplied to the hydraulic cylinder comprises a seat surface and a sealing surface permanently pressed against each other with variable contact pressure, with which the pressure medium flow can be generated as controlled leakage. The sealing surface is made of a material that can be deformed by contact pressure. In the control seat valve, the controlled leakage is set in a control position at least substantially without lifting movement exclusively by the relative material deformation of the sealing surface on the seat surface, which deformation is set via the contact pressure.
