  • The liquid runs out from the cylinder P to the cylinder Q. 
  • As a result, the piston B rises up and it raises the car placed on the platform.
  • When the car reaches the desired height, the handle H of the lever is no longer pressed. 
  • The valve V gets closed so that the liquid may not run back from the cylinder Q to cylinder P.
