Abstract (en)

[origin: EP2657639A2] The device has an adjustment device that regulates supply of cleaning medium into cleaning channels by positioning the closure element (1) in partly curved hollow casing. A gear element of adjustment device transmits shear forces from stationary portion (2a) to rotating portion (2b) of casing. A drive or output element (6) connected to closure element, transmits shear force in a direction which forms a preset angle with respect to direction of transmission of shear force from first drive or output element (4). The two output elements are connected by a four-bar chain (5). Independent claims are included for the following: (1) heat exchanger; and (2) method for cleaning mass storage of heat exchanger.
