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 thatthe 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： The invention relates to an odor trap device for sanitary fixtures, in particular urinals, having a drainage element which has a pipe section, the pipe section defining a sealing wall, having a sealing diaphragm which is in sealing contact with the sealing wall in a closed position and is pushed away from the sealing wall into an open position when fluid, such as urine, is present, and having a holder for mounting the sealing diaphragm relative to the sealing wall. In order to minimise the risk of odor formation in an odor trap device of this kind and also to reliably discharge small quantities of urine or liquid present, it is provided, in accordance with the invention, that the sealing diaphragm is fixed on the holder, the holder being supported below the sealing diaphragm.

摘要： A valve fitting for filling a sanitary cistern includes a connection element, a shutoff valve including an actuation element, and a float-actuated filling valve. The connection element, shutoff valve and filling valve are interconnected to form a water passage into the cistern. A float is connected to the filling valve. The actuation element of the shutoff valve is rotatable about a rotational axis when the float is in the operating position thereof, the shutoff valve being operationally usable in the valve fitting in at least two different positions, the connection element configured to be mounted at an opening in the left-hand cistern side wall in one of the positions, and at an opening in the right-hand cistern side wall in another of the positions, and the actuation element being accessible from the front of the valve fitting in the at least two positions of the shutoff valve.

摘要： The disclosure relates to an attachment for a base jaw of a pressing tool for pressing fittings in order to produce pipe connections, comprising an attachment body, a pressing section, formed on the attachment body, to form half of a jaw opening, and comprising a connecting section, formed on the attachment body, for a connection to the base jaw. The technical problem of providing attachments for exchangeable jaws, base jaws and systems which allow an improved use for fittings of different nominal widths is solved in that the pressing section and the connecting section are arranged at a distance from one another. The invention also relates to a base jaw and to a system consisting of at least two pairs of attachments and one pair of base jaws.

摘要： A cheek plate for producing a non-detachable pipe joint having an upper cheek half and a lower cheek half, at least one swivel pin which pivotally mounts at least one cheek half, and a receiving region formed between the upper cheek half and the lower cheek half and having a receiving region axis, the at least one cheek half being able to pivot between an open position and a closed position substantially transversely with respect to the receiving region axis. The problem of providing a cheek plate such that the cheek plate permits pressing transverse to the receiving region axis and at the same time a reduction in workpiece size is permitted is solved in that at least one pushing unit is provided, the pushing unit being displaceable at least partially in parallel with the receiving region axis.

摘要： The invention relates to a force generator for generating a linear pressure force, including a housing, an output wedge displaceably arranged in the housing, and a drive wedge for transmitting an externally exerted pressing force into a linear movement of the output wedge. The output wedge is connected to a first pressure element. The housing is connected to a second pressure element. A force applied to the drive wedge causes displacement of the first pressure element relative to the second pressure element. The force generator solves the technical problem of providing a high pressure force and using the known press jaws for this purpose.

摘要： The invention relates to a system for connecting rigid pipes and for connecting flexible pipes. The pipes have corresponding outer diameters, with a press jaw having a press contour, with at least one first fitting for press-fitting to a rigid pipe, the at least one first fitting having a first press sleeve with a first outer contour, with at least one second fitting for press-fitting to a flexible pipe, the at least one second fitting having a second press sleeve with a second outer contour, the at least one second fitting having a second press sleeve with a second outer contour has a second press sleeve with a second outer contour, the outer contour of the first press sleeve and the outer contour of the second press sleeve in each case being adapted at least in sections to the press contour of the press jaw of the press jaw and can be pressed by the press jaw and wherein the outer contours of the first press sleeve and of the second press sleeve correspond at least in sections. This system solves the technical problem of simplifying the on-site effort for installing piping systems. In particular, the task is to specify suitable combinations of fittings for rigid and flexible pipes
