Sanitary installations and shower assembly

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.

1 . A sanitary fixture ( 1 ), comprising a flow regulator unit ( 5 ) arranged in a flow path ( 2 ) that includes a movable adjustment element ( 6 ), a throughflow rate defined by the flow regulator unit ( 5 ) is settable by the adjustment element ( 6 ), a control element ( 8 ) which changes shape depending on a temperature, arranged in the flow path ( 2 ) and operatively connected to the adjustment element ( 6 ), such that an increase in a temperature at the control element ( 8 ) causes a displacement of the adjustment element ( 6 ) towards greater throughflow rates, and a restoring spring ( 13 ) that acts on the adjustment element ( 6 ), wherein the control element ( 8 ) and the restoring spring ( 13 ) are arranged in the flow path ( 2 ) on a same side of the flow regulator unit ( 5 ). 
     
     
         2 . The sanitary fixture ( 1 ) according to  claim 1 , wherein the restoring spring ( 13 ) and the control element ( 8 ) are arranged on a downstream side in relation to the flow regulator unit ( 5 ). 
     
     
         3 . The sanitary fixture ( 1 ) according to  claim 1 , wherein the restoring spring ( 13 ) comprises a helical spring, a zigzag spring ( 36 ) or a disc spring or a stacked arrangement of disc springs. 
     
     
         4 . The sanitary fixture ( 1 ) according to  claim 1 , wherein a cross-sectional area of an opening ( 19 ) is settable by way of the adjustment element ( 6 ), or the adjustment element ( 6 ) has a basic form that narrows. 
     
     
         5 . The sanitary fixture ( 1 ) according to  claim 1 , wherein the adjustment element ( 6 ) passes through an O-ring ( 18 ), wherein the O-ring ( 18 ), in the event of an increasing pressure difference across an opening, narrows an opening. 
     
     
         6 . The sanitary fixture ( 1 ) according to  claim 1 , wherein the flow regulator unit ( 5 ), the control element ( 8 ) and the restoring spring ( 13 ) are arranged in a tubular sleeve ( 21 ). 
     
     
         7 . The sanitary fixture ( 1 ) according to  claim 1 , wherein the control element ( 8 ) or a control connection ( 29 ) between the adjustment element ( 6 ) and the control element ( 8 ) passes through an interior space ( 14 ) in the flow path ( 2 ), said interior space ( 14 ) being enclosed or at least radially bounded by the restoring spring ( 13 ). 
     
     
         8 . The sanitary fixture ( 1 ) according to  claim 1 , wherein the adjustment element ( 6 ) has grooves that extend radially on the outside along the flow path ( 2 ).
