Abstract
A liquefied gas pump includes a piston and a cylinder which form a pump chamber into which a liquefied gas entrance path and a liquefied gas discharge path open. Relative upward and downward motion between the piston and cylinder provides a repetition of alternating suction and discharge stroke. Liquefied gas is sucked into the pump chamber through the entrance path during the suction strokes, and is discharged out of the pump chamber through the discharge path during the discharge strokes. A separate bubble discharge path opens into said pump chamber at a location in the bottom of an upward recess formed in the top portion of the pump chamber. The bottom of the recess is located above the location where the opening of the liquefied gas discharge path is formed.
