ABSTRACT:
A beverage brewing apparatus suitable for use in a vending machine has a frame supporting a vertically movable open-bottom cylinder and a piston slidably disposed within the cylinder. A base assembly is reciprocal horizontally between a brewing position and rest position. Actuation of various components is controlled by a motor through a cam shaft. The downward movement of the piston is controlled by the operation of a cam element, but this operation of the cam applying vertical force to push the piston also applies a horizontal force tending to offset the axial center lines between the piston and cylinder. Therefore means for preventing the piston from lateral horizontal movement relative to the cylinder insures improved sealing between the piston and cylinder.
