the top of the fuel tank 5 as the tank 5 fills sensor 3 provides pressure back to the receiver 1 keeping its 39 control valve piston 8 open allowing the main flow into the tank 5 when the fluid level in the tank reaches the jet sensor 3 it interrupts the pressure back to the receiver 1 which causes the control valve piston 8 to close fig2 is an illustration of receiver 1 in a closed position the receiver has a poppet valve 7 and a control valve 8 when poppet valve 7 is in an open position it allows flow from the inlet at poppet valve 7 to control valve 8 the control valve 8 has an inlet side area 9 and an outlet side area 10 there is a clearance 11 between poppet valve shaft 12 and main body bore 13 into the connecting rod 14 the flow from the main body bore 13 is guided through to outlet fitting 15 return flow 17 is directly affected by flow 18 coming from outlet fitting 15 if the return flow 17 is great enough pilot valve 19 can be pushed into an open state a flow 20 is provided to allow flow out of receiver 1 return flow 17 is received through return fitting 22 a clearance 24 between control valve 8 and connecting rod 14 allows for flow to come from area 9 to area 10 a pilot valve diaphragm 26 is connected to pilot valve 19 fig3 is an illustration of receiver 1 in the open.
