When the cylinder rotates, the pistons move in and out within their bores as the shoes ride against the angled (C) swashblock (201). As the cylinder rotates, the individual piston bores are connected, alternately, to the crescent shaped upper (port A) and lower (port B) in the valve plate. While connected to the upper side (suction) port A, each piston moves outward OUT, drawing fluid from port A into the piston bore until its outermost stroke (D) is reached. At this point, the piston bore passes from the upper crescent port A to the lower crescent port B. While rotating across the lower crescent, each piston moves across the angled swashblock face and then each piston is forced inward IN. Each Figure 2. Cut-a-way of a Typical “PVG” piston then displaces fluid through the lower Pump (92011R) crescent to port B until its innermost stroke (D) is reached. At this point, the piston bore passes from the lower to the upper crescent again and the cycle is repeated. B A Figure 3.
