Small trailer tire inflation system

A tire inflation system for a trailer capable of being pulled by a non-class 8 vehicle, the trailer comprising an axle and a pneumatic tire mounted at each end of the axle, the non-class 8 trailer not being equipped with air brakes, the system comprising:

• a fluid pressure source mounted to the trailer, the fluid pressure source powerable by energy provided by the vehicle;
• a fluid conduit providing sealed fluid communication between the fluid pressure source and each pneumatic tire so as to allow pressurized fluid from the trailer-mounted fluid pressure source to flow from the fluid pressure source to each pneumatic tire;
• and
• a fluid connector providing sealed fluid communication with the pneumatic tires, the fluid connector comprising a first one-way valve configured for sealed fluid communication with an external fluid pressure source so as to allow fluid to flow from the external fluid pressure source to each pneumatic tire, the first one-way valve disposed so as to prevent pressurized fluid from escaping from the fluid connector to atmosphere when the fluid connector is not connected to the external fluid pressure source, the external fluid pressure source being external to both the trailer and vehicle.
