Patent number: 11460122Abstract: A solenoid valve has a housing which comprises a first and a second housing part, wherein a flexible diaphragm is arranged between the first and the second housing part. A movably mounted actuating element is provided which is connected to the diaphragm and detaches the diaphragm from a valve seat in an operating position of the first and the second housing part upon movement into an open position, and which presses the diaphragm onto the valve seat upon movement into a closed position. The first and the second housing part can take up a service position in which the diaphragm is accessible. The diaphragm is connected with a positive fit to the actuating element in a nondestructively detachable manner such that in the service position, the diaphragm can be removed from the actuating element by releasing the positive fit and can be connected thereto by establishing a positive fit. An assembly and a method of replacing a diaphragm are furthermore proposed.Type: GrantFiled: March 11, 2021Date of Patent: October 4, 2022Assignee: Bürkert Werke GmbH & Co.

Patent number: 10041511Abstract: A pneumatic drive and a method for acquiring the power of a pneumatic drive are specified. A piston is movably disposed in a working space and coupled to a path transducer. A pressure sensor is provided for acquiring an internal pressure of the working space. An evaluation unit of the pneumatic drive is adapted to process the value of a path distance of a movement of the piston acquired by the path transducer as well as a variation of the internal pressure in the working space acquired by the pressure sensor. The variation of the internal pressure is associated with the movement of the piston in the working space. Based on these values, a power of the pneumatic drive can be determined.Type: GrantFiled: April 10, 2014Date of Patent: August 7, 2018Assignee: BÜRKERT WERKE GMBHInventors: Klaus Beck, Sebastian Frank, Andreas Ungerer
