Abstract:
1. A downhole tool for moving fluid through the downhole tool, the downhole tool comprising: a tubular member having an upper end, a lower end, an outer wall surface, an inner wall surface defining a longitudinal bore, an upper port disposed between the outer wall surface and the inner wall surface, and a lower port disposed between the outer wall surface and the inner wall surface, the upper port being isolated from the lower port; and a sleeve in rotatable engagement with the inner wall surface of the tubular member, the sleeve at least partially isolating the upper port from the lower port, the sleeve having a sleeve upper end and a sleeve lower end, the sleeve upper end having a sleeve upper end port and the sleeve lower end being closed thereby partially defining a sleeve cavity in fluid communication with the sleeve upper end port, the sleeve cavity having a directional port disposed through a sleeve inner wall surface partially defining the sleeve cavity and a sleeve outer wall surface, the directional port being in fluid communication with the upper port of the tubular member, such that flow through said directional port causes rotation of said sleeve, the sleeve lower end having a fluid movement profile extending no lower than said lower port for facilitating movement of the fluid from the lower end of the tubular member through the lower port of the tubular member.
