Title:
VARIABLE-STROKE-TYPE VALVE DRIVER
Document Type and Number:
WIPO Patent Application WO/2012/070745
Kind Code:
A1
Abstract:
The present invention relates to a variable-stroke-type valve driver whereby the stroke of a valve is varied by simply manipulating the rotation of the valve from the outside of a valve housing to enable a user to easily set a constant flow rate of a fluid. To this end, the variable-stroke-type valve driver includes: a motor; an eccentric shaft coupled to a rotary shaft of the motor, the eccentric shaft being driven together with the rotation shaft; a pusher bundle linked to the driving of the eccentric shaft to vertically move a vertically movable valve body; and a housing in which the motor, the eccentric shaft, and the pusher bundle are disposed, wherein a stopper is disposed on the pusher bundle. Also, the variable-stroke-type valve driver further includes a stroke adjustment hole for restricting the range of upward movement of the stopper, and a hole for fixing the stroke adjustment hole.
