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： A drinking water supply system includes a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, and a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor. The system also includes a presence detector designed to determine information about the presence of a person, or an acoustic sensor designed to measure measuring values for the volume. The central control device is designed to control the drinking water supply system as a function of the information about the presence of a person or as a function of the measured values for the volume. A method for controlling such a drinking water supply system and a computer program that causes the method to be carried out are also provided.

摘要： The invention relates to a cistern, in particular an in-wall cistern, for a toilet or urinal, with a drain valve which has a closure body which can be lifted from a closed position into a flushing position. The closure body is designed as an overflow pipe and has a seal which rests tightly on a valve seat in the closed position, with at least one water intake line, with a valve assembly for letting in drinking water present in the water intake line, with a water discharge line for discharging the drinking water let in by the valve assembly, and with a controller which generates a control signal for actuating the valve assembly as a function of a sensor signal and/or when a predefined time interval has been exceeded since the last withdrawal of drinking water from a cold water or hot water line connected to the water intake line. The valve assembly lets in water from the water intake line as a function of the control signal. According to the invention, the water discharge line is designed in such manner that it discharges the drinking water let in by the valve assembly directly into the overflow pipe. The cistern according to the invention makes it easier to maintain the drinking water hygienic, offers the possibility of carrying out required hygienic flushes with relatively low water consumption and enables a hygienic flushing independent of the flushing water level.

摘要： A pressing tool for joining a pipe and a fitting, including two swivel elements for pressing the pipe and the fitting, a receiving region, formed between the swivel elements, for receiving the pipe and the fitting, at least one swivel axis for rotatably mounting the swivel elements, and a tensioning mechanism for pretensioning the pressing tool. The swivel elements can be swivelled towards one another about the at least one swivel axis to press the pipe and the fitting. In a first, closed position, the receiving region is narrower than in a second, open position, of the swivel elements, wherein the swivel elements are pretensioned towards the closed position by the tensioning mechanism. At least one holding device is provided for holding the swivel elements in the open position against the pretensioning force generated by the tensioning mechanism.

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.
