Abstract

See full text

A flow limiter (1) for setting a maximum flow of water at an outlet from a mixing faucet, wherein the flow limiter in the axial direction comprises a seat (3 a, 3 b) which along its periphery is provided with an annular wall (8a, 8b) and has flow channels (7) arranged inside and along said wall (8a, 8b), an actuator (30, 50) which is rotatably arranged on the seat (3a, 3b), a regulating device (20a, 20b) in the form of a body with a circumferential envelope surface (22, 43) facing the inside of said annular wall (8a, 8b), wherein the actuator (30, 50) comprises means (34a, 34b) for moving the regulating device (20a, 20b) in the axial direction, and wherein an annular cavity is formed between walls formed by the envelope surface (22, 43) of the regulating device and the wall (8a, 8b) of the seat, in which annular cavity an O-ring (24) is arranged, wherein one of the walls (43, 8a) of the annular cavity has open axially extending grooves (9, 44) with a cross-section area increasing in the direction of flow, whereby the O-ring (24) in its plane is adapted to slidably connect to said grooves (9, 44) and to adopt one of predetermined positions in the axial direction along said grooves (9, 44) upon rotation of the actuator (30, 50), and wherein said position corresponds to a maximum flow determined by a cross-section area for channels which is limited by the O-ring (24) and the walls of the grooves (9, 44) in the plane of the O-ring (24).
