Abstract
A pneumatic basting fluid injection apparatus including a fluid piston and cylinder assembly having a fluid inlet connected to a basting fluid source, and a fluid outlet connected to an injection apparatus, a pneumatic piston and cylinder assembly operatively connected to the fluid piston and cylinder for drawing fluid into and discharging fluid from the fluid piston and cylinder assembly, a four-way valve connected to control the operation of the pneumatic piston and cylinder assembly, a manual control valve connected to move the four-way valve to a first position to raise the pneumatic piston and cylinder assembly to fill the fluid piston and cylinder assembly and a pressure sensing valve responsive to a drop in pressure in the pneumatic piston and cylinder assembly, and being connected to move the said four-way valve back to the original position to reverse the motion of the pneumatic piston and cylinder assembly and thereby discharge fluid from the fluid piston and cylinder assembly to the injection assembly, a clean-in-place valve connected to the four-way valve and second pressure sensing valve connected to the clean-in-place valve and being responsive to a change in pressure in the pneumatic piston and cylinder assembly to move the four-way valve to the first position at the end of the discharge stroke.
