Aviatorial valve assembly

A system for protecting a pneumatic-gyroscopic aircraft instrument, the instrument being driven by a driver source, the system comprising:

• means for allowing a pneumatic flow to the instrument during flight;
• and
• means for selectively redirecting, without interrupting, the pneumatic flow to the instrument;
• wherein said means for selectively redirecting, without interrupting, the pneumatic flow comprises means for locking a valve to prevent a flow relationship between the driver source and the instrument.

A system for use in an aircraft, comprising:

• a source for providing a pneumatic flow;
• a pneumatic gyroscopic aircraft instrument;
• and
• an adjustable valve that enables a flow arrangement between the source and the instrument, wherein the valve is adjustable between at least a first position that allows the pneumatic flow to the instrument and at least a second position that prevents the pneumatic flow to the instrument without interrupting the pneumatic flow from the source;
• wherein the valve further enables a flow arrangement between the source and a dummy load.

A system for use in an aircraft, comprising:

• a source for providing a pneumatic flow;
• a pneumatic gyroscopic aircraft instrument;
• an adjustable valve that enables a flow arrangement between the source and the instrument, wherein the valve is adjustable between at least a first position that allows the pneumatic flow to the instrument and at least a second position that prevents the pneumatic flow to the instrument without interrupting the pneumatic flow from the source;
• wherein the source connects to the valve through an open aperture and the instrument connects to the valve through a first closeable aperture;
• and
• a dummy load connected to the valve through a second closeable aperture.

A system for use in an aircraft, comprising:

• a first flow arrangement between a driver source and a pneumatic gyroscopic aircraft instrument;
• a second flow arrangement between the driver source and a dummy load;
• and
• means for selectively redirecting a pneumatic flow between the first flow arrangement and the second flow arrangement without interrupting the pneumatic flow;
• wherein the means prevents the pneumatic flow to the first flow arrangement when the pneumatic flow is redirected to the second flow arrangement.
