A flow regulator (1) having a regulator housing (2) with a control peg (4) in a passage channel that encompasses an annular flow restrictor (5) made of elastic material. The flow restrictor defines a control gap (6) located between itself and at least one part that is fixed to the housing. The passage cross-section of the gap can be modified by deformation of the flow restrictor resulting from the difference in pressure during cross flow. Spaced recesses (7, 8) oriented in the flow direction are provided in a peripheral direction on the surfaces of the part fixed to the housing defining the control gap (6). The regulation recesses are on the inner surface of the regulator housing (2) and on the peripheral surface of the control peg. The desired flow rate is achieved at comparatively low liquid pressure and remains practically constant in case of increased or fluctuating liquid pressures.
