ABSTRACT:
A liquid metering dispenser is actuated by a trigger. The trigger releases a valve rod which is spring actuated to close a fluid pressure inlet, opening the discharge outlet of the dispenser to release a stored measured charge of liquid by operation of a spring actuated piston. The trigger is cocked by drawing the valve rod to close the discharge valve and open the liquid pressure inlet; the liquid under pressure enters the storage chamber, compressing the piston spring until it strikes an adjustable stop. The piston and spring assembly is readily removable for cleaning and servicing.
