Flow-Volume Regulator

A sanitary insertion cartridge, which is insertable into a sanitary liquid line and has a flow rate regulator with an elastic restrictor that delimits a control gap that changes under pressure of a fluid flowing between the restrictor and a wall of a housing of said flow rate regulator wherein:

• the flow rate regulator includes at least one bypass channel that has at least one channel inlet arranged upstream of the control gap relative to a direction of fluid flow, and at least one channel outlet arranged downstream of the control gap relative to a direction of fluid flow;
• the bypass channel has a valve, which is moveable in response to pressure of said fluid flow, against a reset force, from an open position into a closed position;
• in its closed position the valve closes the bypass channel;
• the flow rate regulator is arranged between a prefilter or filter screen and a jet regulator having at least one jet divider;
• the channel inlet of the bypass channel is arranged upstream of the prefilter or filter screen;
• and
• the channel outlet of the bypass channel is connected downstream from at least one of the jet regulator and the at least one jet divider of the jet regulator.

A sanitary insertion cartridge which is insertable into a sanitary line, said cartridge comprising:

• a screen element which is one of a prefilter screen and a filter screen;
• a jet regulator having at least one jet divider;
• and
• a flow rate regulator;
• wherein, the flow rate regulator includes a housing and an elastic restrictor that delimits a control gap which changes under pressure of a fluid flow between the restrictor and a wall of said housing;
• the flow rate regulator further includes at least one bypass channel that has at least one inlet arranged upstream of the control gap relative to a direction of fluid flow, and at least one outlet arranged downstream of the control gap relative to a direction of fluid flow;
• the bypass channel has a valve, which is moveable in response to pressure of said fluid flow, against a reset force, from an open position into a closed position;
• in its closed position the valve closes the bypass channel;
• the flow rate regulator is arranged between said screen element and said jet regulator;
• the channel inlet of the bypass channel is arranged upstream of the screen element;
• and
• the channel outlet of the bypass channel is connected downstream from at least one of the jet regulator and the at least one jet divider of the jet regulator.
