Patent ID: 8418721

Claim:
A valve assembly comprising: a valve body ( 4 ) including a first section ( 6 ) and a second section ( 8 ), the first section ( 6 ) including an inlet member ( 12 ) and an outlet member ( 13 ) and the second section ( 8 ) including an inlet element ( 28 ) and an outlet element ( 29 ); and a control system ( 44 ) arranged between the first section ( 6 ) and the second section ( 8 ) of the valve body ( 4 ), the control system ( 44 ) including a flow direction member ( 48 ) having a through flow portion ( 60 ) including a first orifice ( 63 ) and a second orifice ( 64 ) and a bypass portion ( 73 ) including a first opening ( 76 ) fluidically connected to a second opening ( 77 ) through a bypass conduit ( 75 ) that is selectively shifted along a substantially linear path between one of a full through flow mode and a bypass mode, wherein in the full through flow mode the flow direction member ( 48 ) passes a complete fluid flow from the inlet member ( 12 ) through the first orifice ( 63 ) to the outlet element ( 29 ) and from the inlet element ( 28 ) through the second orifice ( 64 ) to the outlet member ( 13 ), and when in the bypass mode the flow direction member ( 48 ) passes the fluid flow from the inlet member ( 12 ) through the first opening ( 76 ) into the bypass conduit ( 75 ) to the second opening ( 74 ) and to the outlet member ( 13 ), wherein the flow direction member ( 48 ) is selectively positioned in a partial bypass mode when the flow direction member ( 48 ) passes a first portion of the fluid flow from the inlet member ( 12 ) to the outlet member ( 13 ) and a second portion of the fluid flow from the inlet member ( 12 ) to the outlet element ( 29 ).
