Abstract
A strut length and pressure regulation system is disclosed. The system may regulate the length of a strut by controlling the amount of gas in the strut. The system may monitor the length of the strut and/or pressure of gas in the strut and may change the amount of gas in the strut in response to the length of the strut and/or pressure of gas in the strut. In this manner, the effects of temperature changes may be compensated.
Claims14
A strut length and pressure regulation system comprising:
- a pressure source comprising a gas reservoir;
- a valve configured to selectively connect the pressure source in fluidic communication with a strut;
- and
- a valve control apparatus configured to actuate the valve in response to position data wherein the valve comprises:
- a floating piston comprising a floating piston passage;
- a spring disposed between the floating piston and a housing;
- wherein the valve control apparatus comprises:
- the housing;
- a control reservoir in fluidic communication with the floating piston;
- an orifice in fluidic communication with the control reservoir and in fluidic communication with a strut condition feedback interconnection;
- wherein the strut condition feedback interconnection conveys gas from the strut to the orifice in fluidic communication with the control reservoir, wherein the floating piston is translatable in response to a pressure of the gas in the control reservoir, and wherein the floating piston passage is alignable with a first valve input interconnection and a first valve output interconnection.
8 more elements
A method of strut length and pressure regulation comprising:
- receiving, at a controller, a position signal;
- receiving, at the controller, a pressure signal;
- and
- controlling, by a valve control apparatus in electrical communication with the controller, a first strut length of a strut in response to at least one of:
- the position signal or the pressure signal wherein the valve comprises:
- a floating piston comprising a floating piston passage;
- a spring disposed between the floating piston and a housing;
- wherein the valve control apparatus comprises:
- the housing;
- a control reservoir in fluidic communication with the floating piston;
- an orifice in fluidic communication with the control reservoir and in fluidic communication with a strut condition feedback interconnection;
- wherein the strut condition feedback interconnection conveys gas from the strut to the orifice in fluidic communication with the control reservoir, wherein the floating piston is translatable in response to a pressure of the gas in the control reservoir, and wherein the floating piston passage is alignable with a first valve input interconnection and a first valve output interconnection.
