1. A flow rate regulator (1) for adjusting a flow rate of a fluid, the flow rate regulator (1) comprising:
a control element (2);
a control opening (3) formed at least partially by a housing (4), a clear opening dimension (5) of the control opening (3) is modifiable by the control element (2) as a function of pressure acting on the control element (2);
the control element (2) forms at least a partial section of an edge (7) defining the control opening (3); and
the control element (2) has at least two segments (6) which are detached from each other and are each deformable as a function of pressure, wherein the at least two segments differ in at least one of: a material thickness thereof; a stiffness thereof or a material thereof.
