Foot pump and stow system

A low profile foot pump, comprising:

• a base configured with a substantially planar support portion to rest stably on a flat surface and having an air outlet port, an airline outlet, an air passage therebetween, and a check valve disposed in said air passage;
• a pump cylinder having an upper end and a lower end, said lower end sealingly and removably coupled to said base, said pump cylinder having an interior side and an interior volume, said interior volume in fluid communication with said air outlet port of said base;
• a cap removably coupled to said upper end of said pump cylinder, said cap configured with a center hole to provide support structure for a reciprocating piston;
• a piston having a piston rod slidingly disposed through said center hole, said cap further including a plurality of air inlet ports disposed around said center hole, said piston rod having an upper end and a lower end;
• a foot platform disposed on said upper end of said piston rod;
• an annular air filter element;
• a retainer ring disposed under and spaced apart from said cap in a position fixed in relation to said cap so as to capture said air filter element, said retainer ring having a plurality of through holes;
• a piston head affixed to said lower end of said piston rod and having air channels disposed through said piston head and around its circumference, a circumferential O-ring groove and a deformable piston O-ring disposed in said circumferential O-ring groove, said circumferential O-ring groove in fluid communication with said air channels, and said air channels in fluid communication with said through holes in said retainer ring, said piston O-ring sized so as to create static friction between said piston O-ring and said interior side of said interior side of said pump cylinder;
• and a spring disposed between said base and said piston head;
• wherein said circumferential O-ring groove is configured such that upon a suction stroke said piston O-ring moves to bring said interior volume of said pump cylinder into fluid communication with outside air and closes said check valve to prevent the passage of air from said airline outlet into said interior volume, and upon a delivery stroke said piston O-ring moves to prevent outside from entering said interior volume and drives air from said interior volume through said air outlet port, through said air passage and past said check valve, and through said airline outlet.
