Solenoid operated pressure cartridge for inflation system

A solenoid operated pressure cartridge, comprising:

• a pressure cartridge body defining a pressure cavity and an inlet;
• a fill valve disposed at the inlet whereby the pressure cavity is configured to receive a pressurized fluid;
• a valve seat;
• a plunger fluidly communicative with the pressure cavity and initially in a closed position relative to the valve seat;
• and
• an electromagnet configured to generate a magnetic flux to move the plunger into an open position relative to the valve seat;
• wherein, in response to the plunger moving into the open position relative to the valve seat, the solenoid operated pressure cartridge is configured to release the pressurized fluid from the pressure cavity.

An inflation valve arrangement for inflating an inflatable device, the inflation valve arrangement comprising:

• a pneumatic valve body comprising a main fluid channel having a valve body inlet connected to a source of inflation gas and valve body outlet connected to the inflatable device;
• a spool located in the main fluid channel, the spool configured to translate along a longitudinal axis of the pneumatic valve body;
• an actuation cavity housing connected to the pneumatic valve body, the actuation cavity housing comprising an actuation cavity;
• a piston rod extending from the actuation cavity at least partially into the main fluid channel in an initially extended position;
• a solenoid actuated pressure cartridge connected to the actuation cavity housing, the solenoid actuated pressure cartridge comprising:
• a pressure cavity containing a source of actuation gas;
• a valve seat;
• a plunger fluidly communicative with the pressure cavity and initially in a closed position relative to the valve seat;
• and
• an electromagnet configured to generate a magnetic flux to move the plunger into an open position relative to the valve seat;
• wherein, in response to the plunger moving into the open position relative to the valve seat, the solenoid operated pressure cartridge is configured to release the actuation gas from the pressure cavity into the actuation cavity.
