Inventors:

Derek Leslie Aldred - Granada Hills CA, US
Jeffrey Allen Rader - Arleta CA, US

International Classification:

F16K 15/00

US Classification:

137 1, 137528

Abstract:

A pump assembly includes a rotating component and a stationary component coupled to the rotating component such that the stationary component substantially circumscribes at least a portion of the rotating component. A high pressure outlet extends at least partially through the rotating and stationary components. An inlet is positioned a predefined distance from the high pressure outlet. The inlet extends at least partially through the rotating and stationary components. A solid fuel flow is channeled from the inlet to the outlet as the rotating component rotates. A flow control member is coupled to the rotating and stationary components in a first predefined position. The flow control member is selectively moveable from the first predefined position to a second predefined position to form a seal within the pump assembly such that the solid fuel flow and a fluid flow are substantially restricted from being channeled back into the inlet.
