ABSTRACT:
This refrigeration system expansion valve (10) includes a body (12) having an inlet (20) and an outlet (22) and a valve assembly (24) within the body (12). The valve assembly (24) includes a first port (28) communicating with the inlet (20) and a second, larger port (30) communicating with the outlet (22) and further includes a pin (32) having a first pin portion (34) received by the first port (28) and a second pin portion (36) received by the second port (30). A stepper motor (100) attached to the valve body (12) cooperates with an actuator assembly (60) attached to the pin (32) to induce longitudinal movement into the pin and thereby control refrigerant flow through the valve.
