Publication number: 20230175786Abstract: The invention relates to an exchanger device comprising a first and a second end piece (1, 2) and an exchanger body (3, 4) arranged in-between. At least one first and one second channel (150, 151) in the exchanger body (3, 4) connect inlets and outlets (10, 11, 20, 21) of the two end pieces (1, 2), wherein the inlets and outlets (10, 11, 20, 21) are arranged in end faces of the end pieces (1, 2), which face away from the exchanger body. The exchanger body forms a multi-helix, in particular a double helix or multiple concentric ring surfaces, wherein the windings of the multi-helix or the concentric ring surfaces form separating walls (3, 4) between the at least one first and the at least one second channel (150, 151). The device according to the invention allows for the formation of exchanger devices with high efficiency yet also with a small outer diameter. The manufacturing process is also simplified.Type: ApplicationFiled: March 16, 2021Publication date: June 8, 2023Applicant: VIESSMANN CLIMATE SOLUTIONS SEInventors: Jörg EVERTZ, Dominik EGGERT, Uwe WERNER

Patent number: 9133919Abstract: At least a motor, a gear unit and an adjustment connection form an actuator. The gear unit is fitted with at least two mutually movable gear parts, as well as a spring acting on two of these that counteracts their movement out of an idle state. The gear unit is designed such that when an adjustment connection is blocked the motor moves the gear parts out of the idle state during operation to an operating point. In addition, the gear unit is designed such that during the movement out of the idle state it reduces the extent to which the movement is counteracted from a particular point upstream of the operating point.Type: GrantFiled: June 22, 2012Date of Patent: September 15, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Markus Bretz, Jörg Evertz, Jörg Hindermann, Andreas Pally, Martin Sprecher

Patent number: 8490943Abstract: A valve of a heating, ventilation and/or air conditioning system includes an actuator with a housing and a shaft which is arranged at least partially in the housing and which can be coupled directly or indirectly to the valve such that the valve can be adjusted during a rotation of the shaft. A hand-operated element can be coupled to the shaft via an overload clutch arranged between the hand-operated element and the shaft which limits a torque which is transmitted onto the shaft by the hand-operated element to a predetermined maximum value. The overload clutch has a coupling element and a replaceable spring element which presses the coupling element against the shaft such that the maximum value for the transmittable torque is dependent on the replaceable spring element.Type: GrantFiled: February 11, 2011Date of Patent: July 23, 2013Assignee: Siemens AktiengesellschaftInventors: Daniel Bühler, Jörg Evertz, Martin Sprecher, Uwe Werner
