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