A device uses hydraulic actuation for the closure of a vessel by a rotation-symmetric reciprocating piston mechanism of an extremely compact type, which includes a reciprocating hydraulic piston and an intensifier piston, which are in each case moved in cylinders. The hydraulic piston is driven water-hydraulically and the intensifier piston pneumatically, these two forming a direct axial functional unit via a fluid, which is located in a chamber between the lower face of the hydraulic cylinder and the upper face of the intensifier piston. The upper face of the hydraulic piston forms at least partially the plug-type closure of the vessel or is rigidly connected to a closure element of the vessel.

High pressure device and method for clean room applications

A high-pressure generating apparatus including a high-pressure chamber, a low-pressure chamber located beneath the high-pressure chamber and having a diameter substantially larger than the diameter of the high-pressure chamber, a tandem piston having first and second portions displaceable in the high-pressure and low-pressure chambers, respectively, for building-up pressure therein, and a yoke embracing the high-pressure and low-pressure chambers for applying a pressure force to the high-pressure chamber cover and the low-pressure chamber bottom upon built-up of pressure in the high pressure and low-pressure chambers.

High pressure generating apparatus

A vertically disposed centrifugal pressure filter for suspensions has a closed casing containing a sectional hollow rotary shaft, the long section of which is equipped with filter disks within the casing. A relatively short shaft section has a plug-in connection with the lower end of the long shaft section and has bearing in an outside bearing casing detachably connected to the filter casing. Dynamic sealing means is provided between the short shaft section and the bearing casing, so that when the bearing casing and short shaft section are disconnected from the filter casing and long shaft section, the seal for the short shaft section is not disturbed. The filtrate passes through the shaft sections and to the outside through the bearing casing.
