摘要： The invention relates to a drain valve (1) for a sanitary cistern, in particular a concealed cistern, having a valve housing (2) with a drain opening (4), the drain opening (4) being delimited by a valve seat (6), and a valve body (7), which rests in a sealing manner on the valve seat (6) in the closed state of the drain valve, the valve housing (2) having a housing chamber (11), arranged upstream of the valve seat (6) in the direction of flow, for receiving water. To allow the drain valve to be arranged outside the cistern and to enable access to the drain valve for maintenance as well as removal via an inspection opening that can be covered by a toilet bowl or urinal bowl, the invention suggests that
the valve body (7) is provided with an auxiliary chamber (12) for receiving water, the receiving volume of which is smaller for water in the open state of the drain valve (1) than in the closed state of the drain valve (1), the auxiliary chamber (12) being delimited by a flexible and/or movable wall section, and wherein the auxiliary chamber (12) is associated with an auxiliary drain valve (16) which in a first position permits an inflow of water into the auxiliary chamber (12) and in a second position permits an outflow of water out of the auxiliary chamber (12).

摘要： A press fitting, including a tubular component and an end portion of the tubular component which can be compressed to make a connection. The end portion has an opening to receive a tube and a first region having an annular ridge to receive a sealing ring. A second region is arranged on the side of the ridge adjacent the opening and a third region is arranged on the side of the ridge remote from the opening. The overall wall thickness of the press fitting in the second region is increased at least in a section or sections in comparison with the wall thickness of the tubular component in the third region.

摘要： The invention relates to a system for producing a sealed connection of a press connector to a workpiece, in particular to a pipe, preferably to a plastic pipe, with a pressing tool for pressing a press connector and with a pressure tool for driving the pressing tool. The pressure tool is arranged to output a hydraulic pressure at a pressure generation point The pressing tool is arranged to receive a hydraulic pressure at a pressing location and to press a press connector accordingly. The pressure tool and the pressing tool are connected via a hydraulic pressure transmission connection, the pressure generation location and the pressing location being remote from each other. A corresponding method for producing a tight connection of a press connector to a workpiece, in particular to a pipe made of a flexible material, preferably a plastic pipe, as well as a press force translator and a press tool are also described.

摘要： The invention relates to a fitting to be connected to at least one pipe, in particular a plastic pipe or plastic-metal composite pipe, having a main body, having at least one supporting body connected to the main body for insertion into a pipe end and having at least one pressing sleeve connected to the main body for receiving the pipe end, the pressing sleeve having a cylindrical pressing section. The technical problem of improving the fitting for pressing, in particular with small motor-driven or manually driven pressing tools, is solved by the fact that the pressing sleeve is made of a metal with a microhardness of less than 65 HV 1, in particular less than 50 HV 1, preferably in the range from 40 to 50 HV 1 measured according to Vickers, and that the ratio of wall thickness of the pressing section to the outer diameter of the pressing section is less than 0.06, preferably in the range from 0.03 to 0.06. The invention also relates to a method for establishing a connection.
