Abstract: A flow limiter for limiting a volumetric flow through a liquid line, comprising a carrier having a passage and a flat spring attached to the carrier. The flat spring has a spring tongue and the passage has an opening, wherein the spring tongue is above the opening such that the spring tongue increasingly lies against the carrier as differential pressure rises, thereby reducing the opening and continuously reducing the passage within a defined pressure range. A body is arranged upstream of the spring tongue, or the spring tongue is oriented in the flow direction so that the spring tongue offers a direct contact surface to a substantially reduced flow cross-section. Thus the spring tongue is deflected, or rested against the carrier, to a lesser extent at low differential pressure values so that at a low differential pressure, a constant volumetric flow rate and an expanded operating range having a constant volumetric flow rate is achieved.

Abstract: The invention relates to a flow restrictor (1) for restricting a volume flow through a liquid line, said flow restrictor comprising a support (10) having a passage and a bent flat spring (11) attached to the support (10). The flat spring (11) comprises at least one spring tab (12) and the passage at least one opening (13), the spring tab (12) and the opening (13) having a substantially identical extension along a longitudinal direction. The spring tab (12) is designed and arranged above the opening (13) in such a manner that it increasingly rests against the support (10) with increasing differential pressure, thereby gradually making the opening (13) smaller and continuously reducing the passage within a defined pressure range. The dimensions of the opening (13) are adjusted corresponding to the size of the spring tab (12), thereby allowing a compact flow restrictor (1) which is less susceptible to dirt.

Abstract: The invention relates to a connector for the detachable connection of at least one light waveguide to at least one optoelectronic component, which is arranged and electrically contacted as a chip directly to the surface of a support or a circuit board and which has an optical axis perpendicular to the support or circuit board. The light waveguide is provided with a fiber-optic plug connector at the end thereof for connection. The connector includes a base piece fixed to the surface of the support or circuit board, enclosing the optoelectronic component and includes a through-hole for the optical signal for exchange between the optical component and the light waveguide. The connector device also includes a coupling piece which connects to the base piece facing outwards and which comprises a socket opening for plugging in the standardized fiber optic plug connector.
