Abstract
A fluid control system for controlling pressurized fluid within a mobile energy transfer system, the control system including a compressor configured to pressurize a fluid, an accumulator configured to store the pressurized fluid from the compressor, and a pneumatic control valve for controlling movement for a connecting arm assembly and movement of a plurality of extendable brushes. The fluid control system may include the use of an extension fluid pathway for extending the downstream components and a retraction fluid pathway for retracting the downstream components and regenerating pressure for the control system.
Claims20
A pneumatic control system for a mobile machine energy transfer system, the mobile machine energy transfer system including a boom, a connecting arm assembly including a plurality of connecting arms, and a contactor assembly including a plurality of extendable brushes, the pneumatic control system including:
- a compressor configured to pressurize a fluid;
- an accumulator configured to store the pressurized fluid from the compressor;
- and
- an pneumatic control valve for controlling movement of the plurality of connecting arms and movement of the plurality of extendable brushes, wherein the pneumatic control valve includes an extension fluid pathway for conveying the pressurized fluid from the accumulator to the plurality of extendable brushes,
- wherein the extension fluid pathway fluidly connects the pneumatic control valve to at least one of the plurality of connecting arms or to the plurality of extendable brushes.
A pneumatic control system for a mobile machine energy transfer system, the mobile machine energy transfer system including a boom, a connecting arm assembly including a plurality of connecting arms, and a contactor assembly including a plurality of extendable brushes, the pneumatic control system including:
- a compressor configured to pressurize fluid;
- an accumulator configured to store the pressurized fluid;
- and
- a pneumatic control valve for controlling movement of at least one of the plurality of connecting arms or the plurality of extendable brushes,
- wherein the compressor, the accumulator, and the pneumatic control valve are connected along a first fluid pathway for conveying the pressurized fluid to at least one of the connecting arm assembly or the contactor assembly, and wherein the pneumatic control valve includes a second fluid pathway, different from the first fluid pathway, for conveying the pressurized fluid away from the connecting arm assembly and away from the contactor assembly.
A pneumatic control system for a mobile machine energy transfer system, the mobile machine energy transfer system including a boom, a connecting arm assembly including a plurality of connecting arms, and a contactor assembly including a plurality of extendable brushes, the pneumatic control system including:
- a compressor, wherein the compressor is configured to pressurize fluid;
- an accumulator;
- a pneumatic control valve for controlling flow of the pressurized fluid into the plurality of connecting arms and for the plurality of extendable brushes;
- and
- a brush pressure relay valve for regulating pressure of the pressurized fluid within the plurality of extendable brushes of the contactor assembly.
