Patent ID: 7228870

Claim:
A fuel saving valve assembly for preventing excess gas leakage at conventional gasoline dispensing pumps comprising: an outer tubing having a distal end and a proximal end and a uniform inner diameter; a spring having a distal end and a proximal end disposed within said outer tubing, said spring having a predetermined tension such that it can be extended by pressure of gasoline applied thereto; a rigid crossbar, for holding said distal end of said spring, operatively connected to said spring and operatively connected to said distal end of said outer tubing; and a substantially spherical, metallic valve ball having a diameter greater than said predetermined inner diameter, said metallic valve ball being connected to said proximal end of said spring, for forming a tight seal, in its quiescent state, between said ball and said proximal end of said outer tubing, and, when gasoline pressure is applied thereto, for creating a gap between said metallic valve ball and said proximal end of said outer tubing so as to allow said gasoline to flow freely into the filler tube of a vehicle.
