Abstract:
1. Flow regulator ( 10 , 40 , 50 ) comprising a regulator housing ( 1 ) with a central body ( 3 ), having a grooved profiled core, in a passage channel ( 2 ), the central body is surrounded by an annular throttle body ( 4 ) made from elastic material, the throttle body ( 4 ) bounds a control gap ( 6 ) between itself and an adjacent peripheral surface ( 5 ) provided with control recesses ( 7 ) spaced apart from each other in a circumferential direction and oriented in a flow direction (Pf 1 , Pm 2 ), a passage cross-section of the control gap can be changed by the throttle body ( 4 ) deforming under a pressure difference created by the flow, an open passage cross-section of the control gap ( 6 ) can be changed by changing a relative position of the throttle body ( 4 ) and the peripheral surface, the relative position of the throttle body ( 4 ) and peripheral surface ( 5 ) can be set as a function of the flow direction (Pf 1 , Pf 2 ) of the fluid flowing through the passage channel ( 2 ), and the central body ( 3 ) is constructed as a control peg, control cone, or a control body, which includes the control recesses ( 7 ) and which includes at least two sub-sections with different cone, peg, or control body cross-sections for changing between at least one of two flow rates or at least two pressure ranges.
