Abstract: A jet regulator (1) is provided including a jet regulator housing having an interior in which there is provided a perforated plate (5) with a plurality of throughflow holes (6) for dividing up the water that flows through, of which at least one of the throughflow holes (6), at least in an outflow-side hole portion, widens in a tapered or conical or stepped manner toward an outflow side. On the outflow side of the perforated plate (5) and at a distance therefrom, there is provided an encircling impingement chamfer (19) which narrows a clear housing cross section in a region of the impingement chamfer progressively in the flow direction.

Abstract: A sanitary fixture (1), including a flow regulator unit (5) and a movable adjustment element (6) that adjusts a flow rate and has a control connection to a temperature-sensitive control element (8). The invention provides arranging a return spring (13) on a same side of the flow regulator unit (5) as the control element (8), with respect to the flow direction, and/or designing the control element (8) to assume at least one intermediate position.

Abstract: In the case of a sanitary fixture (1), it is provided that at least one covering surface (7), by way of which at least one flow opening (4) of a flow element (3) is openable and at least partially closable in a temperature-dependent manner, is formed on a covering element (6) made of a temperature-sensitive material (cf. FIG. 1).

Abstract: A jet regulator (1), having a perforated plate (5) arranged therein with throughflow holes (6) extending through the perforated plate for dividing the water flowing therethrough, including a central, non-perforated impingement surface (14) on the perforated plate (5), which non-perforated impingement surface is surrounded by a first annular wall (15), which has passage openings (16) that are oriented in a radial direction and extend through the first annular wall, wherein a respective throughflow hole (6), which extends through the perforated plate (5) and is connected to the respective passage opening (16), is provided on the side of each passage opening (16) arranged in the impingement surface plane. The annular wall (15) is surrounded by an annular ring chamber (29) on the outer circumferential side.

Abstract: A sanitary outlet insert which can be mounted on the water outlet of a sanitary outlet fitting, comprising a flow limiter that has an adjusting element which regulates or limits the flow area in cooperation with a counter element. The flow area of the flow limiter can be preselected or varied by an axial change of the relative position of the adjusting element and the counter element; in that additionally a handle is provided on the outlet end face of the outlet insert, said handle being designed as a pushbutton; and in that an adjusting movement on the handle can be converted into a relative axial movement of the adjusting element and the counter element by means of a pushbutton mechanism.

Abstract: A sanitary outlet insert (1) which can be mounted on the water outlet of a sanitary outlet fitting, comprising a flow rate regulator (2) or a flow limiter that has an adjusting element (3) which regulates or limits the flow area in cooperation with a counter element (3?). The aim of the invention is to easily adapt said outlet insert to the prevailing on-site water pressure and/or to the corresponding application in a simple manner. According to the invention, this is achieved in that the flow area of the flow rate regulator (2) or the flow limiter can be preselected or varied by an axial change of the relative position of the adjusting element (3) and the counter element (3?); in that additionally a handle is provided on the outlet end face (7) of the outlet insert (1), said handle being designed as a pushbutton; and in that an adjusting movement on the handle can be converted into a relative axial movement of the adjusting element (3) and the counter element (3?) by means of a pushbutton mechanism.

Abstract: In a sanitary installation part (1) which, along with a functional unit (7), forms a flow volume regulator, it is proposed that a regulating element (13), which can be adjusted along an adjustment path, be coupled to a temperature-sensitive drive unit (15) such that different regulating positions of the regulating element (13) are set in dependence on the temperature of the medium flowing through the installation part (1), wherein the different regulating positions realize in each case different volume-flow dependencies (11, 12, 45, 48) and/or flow resistances (cf. FIG. 1).

Abstract: A jet regulator (100) including a jet regulator housing (2) is disclosed, in the housing interior of which a perforated plate (5) is provided with a plurality of flow-through holes (6) for dividing the through-flowing water. The jet regulator described is characterised in that at least one flow-through hole (6) extends conically towards its outflow side in at least one outflow-side hole section. It is also possible for flow obstacles to be provided on the outflow side of the perforated plate (5) in the jet regulator housing (2) and/or on the outflow front face of the jet regulator housing, which are arranged or concentrated there in a central or middle region and which deflect the through-flowing water into an outer annular zone. This jet regulator (100) enables an aerated and thereby sparkling-soft water jet to be generated even with low flow-through performance and low water pressure.
