Rotary Pump, Rotation pump on the suction-and-push principle, consisting of a cylindrical drum with a supply and output pipe and a crank. Inside the drum is not cylindrical but heart-shaped. A large cylinder in the middle touches the inner wall where the incoming point of the heart sits. A slat is provided in the cylinder, which protrudes through a slot in the cylinder wall and serves as a piston. Cylinder and piston are rotated with a crank around a central heart-shaped core that controls the movement of the piston so that it always forms a wall between cylinder and inner wall of the drum. Now when the cylinder and piston are rotated, the space between the cylinder and the inner wall of the drum is divided by the piston into two chambers, which vary in size depending on the position of the piston. Thus, at the supply, a chamber is created which becomes increasingly larger and therefore sucks in liquid, and when the piston subsequently passes the supply again, this liquid is pushed to the outlet by the piston. At the inlet and outlet, the inner wall of the drum is perforated with a number of holes, these are partially closed off again, which suggests that the pump has been experimented with., anonymous, France (possibly), c. 1850 - c. 1858, brass (alloy), h 15.5 cm × w 22 cm × d 12 cm × d 12 cm
