Rotating pintle injector for gel fuels

Disclosed is a rotary pintle injector for gel fuel, capable of increasing atomization performance for the gel fuel. According to the present invention, the rotary pintle injector for gel fuel comprises: a pintle unit including a pintle rod fixed to be able to vertically rotate and a pintle tip formed on the lower part of the pintle rod; a sleeve surrounding the pintle rod at an interval to form a fuel manifold to surface fuel around the outer circumference of the pintle rod, and moving in a vertical direction; a driving power transfer unit connected to the pintle rod to be able to vertically move within a preset tolerance range, and connected to the sleeve to be vertically moved and interlocked and be independent from each other in a rotational direction; a driving power processing unit selectively coupled to the driving power transfer unit to transfer rotational driving power to the driving power transfer unit; a pressure chamber supplying the fuel to the fuel manifold, formed between the driving power transfer unit and the sleeve to upwardly press the driving power transfer unit by the pressure of the fuel formed in fuel injection; and an outer body surrounding the sleeve at an interval to form an oxidant manifold to supply an oxidant along the outer circumference of the sleeve. The driving power transfer unit is connected to be rotated and interlocked with the pintle rod with respect to the rotational direction when being coupled to the driving power processing unit.
