ABSTRACT:
The regulating valve of a gear pump for an oil burner is urged to a closed position by a spring-loaded plunger. An adjusting screw is associated with the plunger and, when turned, causes the plunger to shift longitudinally so as to adjust the spring force applied to the valve. The screw is threadably received within a nut which is formed integrally with a sleeve. A pump inlet fitting extends through the sleeve to fasten the sleeve to the body of the pump. The inlet fitting and the sleeve coact to prevent rotation of the nut when the adjusting screw is turned.
