초록 ▼

Fuel routing apparatus for use with fuel-injected engines is provided. In accordance with certain of its aspects, the apparatus automatically recycles fuel to the vehicle\s engine when the fuel stream from the vehicle\s storage tank is interrupted. In accordance with other aspects, the apparatus provides automatic hydraulic switching between fuel tanks for multiple fuel tank vehicles. In certain preferred embodiments, the apparatus includes a replaceable fuel filter and provides automatic bleeding of entrained air from the fuel stream which is delivered to the vehicle\s engine.

대표청구항 ▼

Fuel routing apparatus for use with a fuel delivery system which supplies fuel to an engine, said system including first and second fuel storage tanks, first and second low pressure pumps for withdrawing fuel from the first and second storage tanks, respectively, and a high pressure pump or supplying fuel to the engine, said apparatus comprising: (a) first and second feed ports for receiving fuel from the first and second low pressure pumps, respectively; (b) an engine feed port for delivering fuel to the high pressure pump; (c) an engine return port for receiving fuel returned from the engine; (d) first and second return ports for returning fuel to the first and second fuel storage tanks, respectively; and (e) hydraulically operated valve means having a first position in which the first feed port is connected to the engine feed port and the first return port is connected to the engine return port and a second position in which the second feed port is connected to the engine feed port and the second return port is connected to the engine return port, said means being responsive to the hydraulic pressures produced by the first and second low pressure pumps such that the means is in its first position when the first low pressure pump is supplying fuel to the first feed port and the second low pressure pump is not supplying fuel to the second feed port, and is in its second position when the second low pressure pump is supplying fuel to the second feed port and the first low pressure pump is not supplying fuel to the first feed port, said hydraulically operated valve means comprising: (i) a first two-position valve connecting the first feed port to the engine feed port when the valve is in its first position, and connecting the second feed port to the engine feed port when the valve is in its second position; (ii) a second two-position valve connecting the first return port to the engine return port when the valve is in its first position, and connecting the second return port to the engine return port when the valve is in its second position; and (iii) a chamber separated into first and second portions by a diaphragm which is moveable between first and second positions corresponding to the first and second positions of the hydraulically operated valve means, said diaphragm being connected to said first and second two-position valves, the first and second two-position valves being in their first position when the diaphragm is in its first position and being in their second position when the diaphragm is in its second position, the first portion of the chamber being connected to the first feed port and the second portion of the chamber being connected to the second feed port so that the first portion fills with fuel and moves the diaphragm to its first position when the first low pressure pump is supplying fuel to the first feed port and the second low pressure pump is not supplying fuel to the second feed port, and the second portion fills with fuel and moves the diaphragm to its second position when the second low pressure pump is supplying fuel to the second feed port and the first low pressure pump is not supplying fuel to the first feed port.
