AI Technical Summary

Technical Problem

Existing methods for cleaning fluid residues from sealing elements of filling adapters in pressure sensors are either time-consuming or incomplete, leaving residues such as silicone or vegetable oil droplets on the sealing elements.

Method used

A system comprising a filling adapter with a through-opening, a cleaning unit, an insert sieve with a predetermined mesh size, and a receiving unit, which uses a gas flow to remove residues via capillary action and the Venturi effect, ensuring effective drainage of fluid residues from the sealing element.

Benefits of technology

The system efficiently removes fluid residues from sealing elements by combining gas flow, capillary action, and the Venturi effect, providing complete and efficient cleaning without manual intervention.

Abstract

System (1) for cleaning fluid residues on a sealing element (2) of a filling adapter (3), with - the filling adapter (3), wherein the filling adapter (3) has a base body (4) with a through-opening (5), wherein a connection area (6) with the sealing element (2) is arranged in an end region (4a) of the base body (4), wherein the sealing element (2) surrounds an end section (5a) of the through-opening (5), - a cleaning unit (7) which is designed to direct a gas (9) through the through-opening (5), - an insert sieve (8), wherein the insert sieve (8) is a bowl-shaped curved net (10) with a predetermined mesh size, and - a receiving unit (11) with a receiving surface (12) for receiving the filling adapter (3) and a support surface (13) for receiving the insert screen (8), wherein the receiving surface (12) and the support surface (13) are arranged and designed such that the insert screen (8) touches the sealing element (2) when the insert screen (8) is on the support surface (13) and the filling adapter (3) is on the receiving surface (12).
