Water motor

In a water motor:

• a cylinder having a port on the sidewall thereof spaced downwardly from the upper end thereof,
• an outlet conduit connected to the bottom of said cylinder,
• a piston means having an up and down reciprocating motion disposed on the upper end portion of said cylinder, said piston means having a port spaced downwardly from the upper end thereof, and
• a container with an unlimited supply of water immersing said piston means and said cylinder,
• the ports of said piston means and said cylinder being open to permit water in said container to flow through said cylinder into said outlet conduit when said piston means is in its uppermost position, said ports being closed as the piston means moves downward causing said column of water in said outlet conduit to provide a pulling action on said piston means until the port on said piston means mates with the port on said cylinder to permit water to again flow into said cylinder and thereby terminate the pulling action of the column of water on said piston means.

A water motor unit comprising:

• a cylinder having an inlet port,
• an outlet conduit extending from the lower end of said cylinder,
• a sleeve slideable in said cylinder and having an inlet port,
• a piston head disposed above said sleeve and capable of being seated on the upper end thereof,
• a piston rod connected to said piston head and having an up and down reciprocating movement, and
• a container providing a supply of water for immersing said cylinder, said sleeve and said piston head,
• whereby when said piston rod is in its uppermost position the piston head is spaced above the upper end of the movable sleeve and the sleeve is moved partly out of the cylinder enabling water to flow from said container into the top of the sleeve, into the port of the sleeve, and into the port of the cylinder to fill the outlet conduit with a continuous column of flowing water, and
• whereby as the piston rod starts its downward movement it seats the piston head onto the upper end of the sleeve and forces the sleeve down into the cylinder to close the ports of each resulting in the column of flowing water in the outlet conduit pulling the piston head and the sleeve downwardly until the port on the latter is aligned with the port in the cylinder to thereby permit water to flow into the cylinder to terminate the pull of the column of flowing water on the piston head enabling the latter to be lifted by the upward movement of the piston rod.

A fluid motor unit comprising:

• a cylinder having an elongated outlet conduit on the lower end thereof,
• a piston means reciprocally mounted on said cylinder,
• said cylinder and piston means being immersed in a fluid, and
• valving means for controlling the flow of fluid into said cylinder in accordance with the movement of said piston means relative to said cylinder,
• said valving means operable when said piston means is at the top of its stroke to permit fluid to flow into said cylinder and down through said outlet conduit,
• said valving means operable when said piston means starts its downward movement to cut off the flow of fluid into said cylinder and to cause said piston means to be drawn down to the bottom of its stroke by the fluid flowing in said outlet conduit, and
• said valving means operable when said piston means is at the bottom of its stroke to again permit fluid to flow into said cylinder and continue to flow therein while said piston means moves to the top of its stroke.
