Abstract: The high pressure valve (1) has a high pressure region (2) and a low pressure region (3) and a shut-off element (4). The shut-off element (4) is designed for closing and opening a fluid connection between the high pressure region (2) and the low pressure region (3) and to this end it can be moved in an axial direction (Z) between a closed closure position and an opened opening position. A seat gasket (9) is provided to form a seal in the closure position. The seat gasket (9) is a compression sealing seat gasket (9) which is affixed to the shut-off element (4) and is arranged in a recess provided in the shut-off element (4).

Abstract: A releasable connection arrangement includes a first component, which has a collar projecting radially outwards with a first clamping surface and a first bearing surface and a socket disposed at an open end of a second component for retaining the collar by gripping round it axially. A second bearing surface is formed in the socket to co-operate with the first bearing surface. A groove is formed either in the first or in the second bearing surface to receive a seal. A second clamping surface is formed in the socket at an axial distance from the second bearing surface in which a number of ring wedge-shaped tensioning members are distributed over the circumference and are disposed such that first wedge surfaces abut the first clamping surface and second wedge surfaces abut the second clamping surface.

Abstract: The invention is directed to a spray cooler for regulating the temperature of superheated steam with a stream of cooling water. Its primary inventive feature is directed to a throttle area which has a continuously widening cross section disposed on a piston rod and arranged between the cooling water inlet opening and the nozzles of the spray cooler. The throttle area serves to regulate the pressure the cooling water in proportion to the movement of the piston carrying the throttle.

Abstract: A valve housing in the form of a straight- or bent-passage valve accepts in the the valve seat between its steam intake and steam outlet a choking device in the form of a perforated bushing into which a cold-water pipe with jacket-side cold-water exits projects coaxially. A control piston is mounted in such a way that it can move inside the perforated bushing and around the cold-water pipe. The control surface of the piston simultaneously releases the cold-water exits in the cold-water pipe and the reduction bores in the perforated bushing, resulting in cooling of the steam and reduction of its pressure in the high steam-pressure range in accordance with load. The cold water is accordingly injected into the hot steam as it flows in and only then does the steam, enriched with cold water, pass through the reduction bores.
