摘要： The invention relates to a press connection system for non-releasably connecting a fitting to a pipe, with a press jaw, with a press contour formed on the inside of the press jaw. The press contour has a cylindrical press section, with a fitting, with a fitting base body and a press sleeve forming a press chamber. A sealing ring is arranged at the proximal end of the press chamber relative to the fitting base body and a cutting ring is arranged at the distal end of the press chamber relative to the fitting base body. The cutting ring has a central cylindrical section and cutting elements arranged at the distal end and cutting elements arranged at the proximal end. The technical problem of further improving the pull-out resistance and bursting resistance of the pressed fitting is solved by the press contour having a distal press portion adjacent to the cylindrical press portion, which is at least sectionally conical in shape, and a proximal press portion adjacent to the cylindrical press portion, which is at least sectionally conical in shape, in that the distal press portion is formed to form the distal end of the cutting ring radially inwardly when the press sleeve is pressed radially, that the cylindrical press section is formed to form the proximal end of the cutting ring radially inwardly when the press sleeve is pressed radially, and that the proximal press section is formed to form the sealing ring radially inwardly when the press sleeve is pressed radially. The invention also relates to a swaged fitting.

摘要： A drinking water supply system with a drinking water line system includes multiple drinking water removal points connected to the drinking water line system, at least one sensor, which is designed to determine measurement values, and a central controller, which is designed to receive and evaluate the measurement values determined by the at least one sensor. The central controller is designed to control the control elements depending on the received measurement values. The drinking water line system has a drinking water line section for supplying drinking water to multiple drinking water removal points. A volumetric flow rate sensor is provided in order to measure the volumetric flow rate of the water in the drinking water line section and/or a pressure sensor is provided in order to measure the water pressure in the drinking water line section. The controller is designed to carry out a measure.

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).
