Pulse combustion burner feed valve

A pulse combustion powered apparatus is disclosed for temperature conditioning and pressurizing fluids. The alternating periods of positive and negative pressure of the combustion gases of a pulse combustion burner drive a reciprocating compressor and the rejected engine heat is recovered by heat exchange with a primary fluid. The compressor may be included in a reversible refrigeration circuit to provide heating and cooling of secondary fluids.
