ABSTRACT:
A sensor for rocket engines having at least one combustion chamber including a pressure-sensitive sensing device responsive to pressure in the combustion chamber for providing an output signal to a control device in response to the pressure in the combustion dropping below and/or rising above at least one predetermined pressure. The pressure-sensitive sensing device includes a piston arranged for displacement between first and second positions. The piston is displaceable from at least the first position to the second position in response to a first predetermined pressure value in the combustion chamber. A restoring force is effective for displacing the piston from the second position toward the first position in accordance with a second predetermined pressure value in the combustion chamber. The piston is arranged for triggering a signal in at least one of the first and second positions thereof.
