Abstract
Bidirectional hydraulic pump that comprises a hydraulic body (1) comprising an inlet port (2) from which receives a water flow, a first outlet port (3) and a second outlet port (4); an impeller housed in said hydraulic body (1), which causes the water flow to move in either one direction or the other; and a valve body (5) that surrounds the impeller. The valve body (5) comprises at least one orifice (6) and said valve body (5) is slidable on the internal surface of the hydraulic body (1) in one direction or the other, due to the action of the water flow, between a first position wherein the orifice (6) is aligned with the first outlet port (3) and a second position wherein the orifice (6) is aligned with the second outlet port (4).
Claims4
A bidirectional hydraulic pump comprising:
- a hydraulic body comprising an inlet port receiving a water flow, a first outlet port and a second outlet port;
- an impeller housed in said hydraulic body which direct said the water flow;
- and
- a valve body that surrounds said impeller, said valve body comprising at least one orifice, and said valve body being slidable on an internal surface of said hydraulic body as directed by said water flow, said valve body comprising on an inner surface at least one projection so that said water flow displaces said valve body, said valve body moving between a first position wherein said orifice is aligned with said first outlet port and a second position wherein said orifice is aligned with said second outlet port.
