Patent number: 10634257Abstract: A proportional valve is provided wherein the valve has an actuating element, a compressed-air connection, a working connection, and an air-removal connection. The valve also has three valve elements arranged one after the other and each can be moved in an axial direction. A first valve element is actuated by the actuating element, a second valve element is actuated by the first valve element, and a third valve element is actuated by the second valve element. In a base position, the valve elements are spaced apart, and, within the valve, a first sealing seat effective between the first valve element and the second valve element and a second sealing seat effective between the third valve element and the housing are arranged such that by varying the position of the first valve element, different switching states can be set.Type: GrantFiled: August 10, 2018Date of Patent: April 28, 2020Assignee: HOERBIGER FLOW CONTROL GMBHInventors: Marcus Grödl, Jochen Schaible, Daniel Haller, Max Schrobenhauser, Collin Dymel, Benedikt Hildebrandt, Györg Molnar, Sebastian Neiss

Patent number: 10474169Abstract: A proportional valve is provided having a pilot control valve that can be controlled by means of a control signal and having a booster valve that can be actuated by means of the pilot control valve. The proportional valve has a compressed-air connection for connecting a compressed-air supply, a working connection, and an air-removal connection. The booster valve has three valve elements, which are arranged one after the other and can each be moved in an axial direction against a spring force.Type: GrantFiled: August 8, 2018Date of Patent: November 12, 2019Assignee: HOERBIGER FLOW CONTROL GMBHInventors: Marcus Grödl, Jochen Schaible, Daniel Haller, Collin Dymel, Benedikt Hildebrandt, Györg Molnar, Sebastian Neiss

Patent number: 9807892Abstract: A drive unit is provided, particularly a drive unit for operating flow-control valves, comprising a housing, an electrical input, an electromechanical converter assembly, a mechanical output, and an electronic controller. The controller comprises an input unit having at least one pushbutton, which penetrates the housing and can be depressed against the action of a restoring device, and comprises a contactless switch that is actuated by the at least one pushbutton. A mechanical stop independent of the switch itself is associated with the position of the pushbutton that actuates the switch.Type: GrantFiled: November 10, 2015Date of Patent: October 31, 2017Assignee: Hoerbiger Automatisierungstechnik Holding GmbHInventors: Marcus Grödl, Berthold Grimmer, Daniel Haller, Bin Lang, Tobias Rossbach, Carlos Martinez, Norbert Zylka, Jochen Schaible

Patent number: 9372487Abstract: The invention relates to a fluidic actuator comprising a drive element (2) that can be supplied with a pressure fluid and a two-stage proportional position controller (3) controlling the supply with pressure fluid to the drive element, said actuator comprising an electro-fluidic pilot stage (10) of the position controller, exactly one electromechanical transducer (14) and exactly one proportional valve (16) actuated by said transducer and having a pressure fluid inlet (18), a control pressure outlet (19) and a discharge outlet (20). A fluidic power stage (11) of the position controller comprises two poppet valves (24, 25) having associated pressure-to-distance converters that are supplied by a common control chamber (34) which is connected to the control pressure outlet (19) of the pre-stage (10).Type: GrantFiled: March 6, 2015Date of Patent: June 21, 2016Assignee: Hoerbiger Automatisierungstechnik Holding GmbHInventors: Daniel Haller, Max Schrobenhauser, Erich Rankl, Marcus Grodl

Patent number: 8220491Abstract: A piezoelectric valve having a housing is provided with an inner chamber, in which ends at least one nozzle communicating with an associated port for a medium and provided with a sealing seat having a seat face, a deformable piezoelectric bending element being received in the inner chamber of the housing in such a way that the nozzle can be closed by a portion of the bending element movable relative to the nozzle in response to deformation of the bending element, and the bending element being provided with padding of an elastically resilient material, at least in its region opposite the nozzle. This sealing seat is disposed at the end face of a nozzle insert, which is disposed to be displaceable substantially perpendicular to the seat face in a receptacle fixed to the housing, a thermally expandable compensating member acting between the receptacle and the associated nozzle insert.Type: GrantFiled: January 20, 2010Date of Patent: July 17, 2012Assignee: Hoerbiger Automatisierungstechnik Holding GmbHInventors: Jochen Schaible, Marcus Grödl
