Device and method for limiting or keeping constant a flowing quantity of liquid

Mould for producing one or more injection-moulded products, the mould comprising:

• an outer housing forming a mould cavity therein;
• and
• a counter-mould disposed in the mould cavity;
• wherein at least a part of the counter mould is movable and adjustable such that at least one dimension of the counter mould is adjustable and at least one of a size and shape of the mould cavity is adjustable,
• wherein the movable part of the counter mould is adjustable from an outer side of the mould,
• wherein at least a part of the counter mould is adjustably movable such that the at least one of the size and the shape of the mould cavity is adjusted without disassembling the mould,
• wherein the movable part is adjusted subject to a variation in at least one of thickness and composition of a valve element of the injection-moulded product,
• wherein a portion of mould is configured to form
• a flow limiter, as the injection-moulded product, for limiting flow of a fluid flowing therethrough,
• a housing of the injection moulded product provided with an inlet, an outlet and a throughflow opening;
• and
• a resilient plate-like valve element of the flow limiter, mounted in the housing, substantially able to close the throughflow opening by resilient movement in a direction of a valve seat arranged adjacency of the throughflow opening in the housing, wherein the valve element is fixed on one side and the valve element is resiliently movable on the opposite side in the direction of the valve seat.

Method for producing one or more injection-moulded products, wherein the injection-moulded product is manufactured in a mould for producing one or more injection-moulded products, wherein at least a part of a counter-mould within a cavity of the mould is movable and adjustable such that at least one of a size and shape of a mould cavity is adjustable the method comprising:

• moving, between the manufacture of two injection-moulded products, at least a part of the mould such that a dimension of the counter-mould and at least one of a size and shape of the mould cavity is adjusted,
• wherein the movable part of the counter mould is adjusted from an outer side of the mould,
• wherein the movable part is adjusted subject to a variation in at least one of thickness and composition of a valve element;
• producing a flow limiter, as the injection-moulded product, for limiting flow of a fluid flowing therethrough;
• producing a housing provided with an inlet, an outlet and a throughflow opening;
• and
• producing a resilient plate-like valve element, mounted in the housing, substantially able to close the throughflow opening by resilient movement in a direction of a valve seat arranged adjacency of the throughflow opening in the housing, wherein the valve element is fixed on one side and the valve element is resiliently movable on the opposite side in the direction of the valve seat.
