LIQUID FLOW RATE CONTROLLER Russian patent published in 2012 - IPC F16K31/00 

FIELD: machine building.

SUBSTANCE: liquid flow controller comprises a cylindrical body connected to the pressure pipe. The internal cavity of the body is divided by a partition, provided with a nozzle at the inlet and outlet parts. Located opposite the nozzle is a shut-off throttling element connected to the electric drive. The electric drive is equipped with the output electrical wires with terminal conductive contacts. The controller contains a camera fitted with a bearing and the turbine. The camera is located at the entrance of the housing with a gap relative to its walls. The turbine is equipped with a shaft, an impeller and an approach channel in a shape of the specified gap. Located in the camera is an anchor escapement mechanism with a toothed wheel fixed to the turbine shaft and a spring-loaded follower associated with the electric drive. The camera is fixed on the body without breaking the integrity of its walls. The shaft is installed in the housing on the bearing. Through said bearing the shaft crosses right through the wall of the chamber. A locking element is designed as a drive fixed to a shaft.

EFFECT: high reliability and smaller size of the liquid flow controller.
