Abstract: A venting unit for venting a machinery space includes a base body mountable in a substantially fluid tight manner to an opening of the machinery space, the base body including a fluid permeable passageway for venting and an opening section configured to close the fluid permeable passageway and being attached to the base body in a substantially fluid tight manner. The venting unit further includes an actuator attached to the base body, and at least one sensor coupled to the actuator and configured to sense at least one harmful gas in the machinery space. The actuator includes an actuation element configured to open the opening section when the actuator receives, from the at least one sensor, a signal indicating a presence of an amount of the at least one harmful gas above a desired threshold.

Abstract: A venting unit for venting an electronics housing includes a base body configured to be connected to a pressure compensation opening of the electronics housing, the base body having an opening, a fluid-permeable cover disposed on the base body, a valve closure plate covering the opening of the base body and being covered by the cover, and a spring member interposed between the valve closure plate and the cover and engaging the valve closure plate and the cover. The cover is configured to be fixed in an actual mounting position among at least two mounting positions providing different heights of the cover above the valve closure plate, so that the actual mounting position of the cover sets a pre-compression of the spring member, the pre-compression corresponding to an opening pressure of the valve closure plate.

Abstract: The invention relates to a thermoplastic elastomeric bellow duct (10) having a corrugated duct segment (12) interposed between two elbowed segments (14, 18), wherein at least one of the elbowed segments (18) is made of thermoplastic elastomeric and connected to an end section (22) of the corrugated duct segment (12) by overmolding the elbowed segment (18) over the end section (22) of the corrugated duct segment (12), and wherein the end section (22) of the corrugated duct segment (12) includes a guiding and sealing arrangement (50) pointing away from the corrugated duct segment (12) in a radial direction (32). The invention further relates to an air duct (80) having such a thermoplastic elastomeric bellow duct (10).

Abstract: The invention concerns a fuel filter 10, in particular for diesel fuels, that comprises a housing 11 and a filter medium 12. The filter medium 12 is arranged by means of a filter medium holder 24 in the housing, wherein the filter medium holder comprises a venting bore 25. Through the venting bore 25 gases that collect in the upper area of the fuel filter can pass from the crude chamber 21 into the clean chamber 22. For avoiding that contaminants can escape through a clean outlet 18 from the fuel filter 10 and damage components downstream, a clean medium 26 is provided that retains such contaminants.
