MULTICHANNEL ROLLER PUMP Russian patent published in 2021 - IPC F04C2/344 F04C2/113 

FIELD: pumps.

SUBSTANCE: invention relates to multichannel roller pump. Pump comprises housing 1 and cover 3, cylindrical rotor 5 arranged on shaft with possibility of rotation inside housing 1, stator 2 with crescent chambers through-thickness chamber for inlet and outlet of working medium, arranged axially symmetrically relative to each other. Stator 2 is secured on housing by detachable connection. Crescent-shaped chambers are interconnected with segmented channels of inlet and outlet of working medium, made on cover in the form of axisymmetric segmental cavities. End part of rotor 5 interacts with end of stator 2 and is equipped with grooves 33, in the walls of which there are slots, in which there are rollers supported by separating thrust rings 6, 7, 8, arranged inside grooves 33. By means of cylindrical recess the center of end part of rotor 5 is installed on axis 11 installed in through hole of stator 2 and opening 31 of cover 3 with possibility of movement and fixation of position relative to axis of stator 2.

EFFECT: invention is aimed at reduction of weight at simultaneous increase of pump efficiency.
