Title:
TRANSMISSION ARRANGEMENT AND METHOD FOR USING A DEVICE MOVED BY A HYDRAULIC CYLINDER
Document Type and Number:
WIPO Patent Application WO/2017/191367
Kind Code:
A3
Abstract:
The object of the invention is a transmission arrangement for a moveable device, such as a door (1 ) opening mechanism (2) and a method for using a device moved with a hydraulic cylinder (3). The method comprises at least the following steps: - producing a signal for moving the device (1 ) in a first or second direction and sending the signal to the control device, - if the signal was a signal to move the device (1 ) in the first direction, the first pump (11, 12) is started by means of a signal from the control device, and the pump produces fluid pressure on the first side of the hydraulic cylinder (3) in order to move the device (1) in the first direction, - if the signal was a signal to move the device (1) in the second direction, the second pump (13, 14) is started by means of a signal from the control device, and the pump produces fluid pressure on the second side of the hydraulic cylinder (3) in order to move the device (1) in the second direction, - monitoring the movement and/or position of the device with a sensor (18), which sends information to the control device about the position and/or movement of the device (1), - making a decision in the control device about the necessary procedure, - starting or stopping the first pump (11, 12) and/or the second pump (13, 14) with the aid of a signal from the control device based on the made decision. Fluid pressure is produced with centrifugal pumps used with electric motors.
