Abstract:
A rotary valve with increased resistance to degradation that can include, a manifold with multiple flow paths, a rotary actuator rotatably mounted within the valve, and a valve seat that is fixedly attached to the manifold, with an end (or component) of the rotary actuator made from silicon carbide diamond (ScD) and the end having a first surface. The valve seat can have a second surface that sealingly engages the first surface. Manufacturing a rotary valve can include combining diamond particles in a press with silicon and applying temperature and pressure to produce a piece of ScD. Interposing a compound between the piece and a structure and brazing them by heating the compound between 700-1200 degrees Celsius. Forming ports and flow paths in the piece by machining the piece with an Electrical Discharge Machining (EDM) tool.

Claim (Index 11):
A method of manufacturing a rotary valve, the method comprising:\n combining diamond particles in a press with silicon as a bonding agent and applying temperature and pressure for a predetermined amount of time to produce a first piece of silicon carbide diamond (ScD) composite; brazing the first piece to a support structure by interposing a compound between the first piece and the support structure and heating the compound to above 700 degrees Celsius and below 1200 degrees Celsius, thereby bonding the first piece to the support structure to produce a rotary actuator, with the first piece forming an end of the rotary actuator; machining a recess and a gap in the end of the rotary actuator with an Electrical Discharge Machining (EDM) tool; engaging a first engagement surface of the rotary actuator with a second engagement surface of a manifold, with the manifold comprising multiple flow paths; and rotating the rotary actuator relative to the manifold, thereby selectively aligning each of the multiple flow paths with the gap or the recess, thereby selectively allowing fluid communication through the rotary valve with respective ones of the multiple flow paths.
