BULBLESS EXPANSION VALVE WITH INTEGRATED BYPASS CHECK VALVE

An expansion valve including a valve body having an inlet, an outlet, a main flow passage extending from inlet to outlet, and a metering orifice in the at least one main flow passage. A power element controls movement of a valve member relative to the metering orifice to control flow of operating fluid passing across the metering orifice when the valve is operating in a forward flow expansion mode. The valve body includes an internal bypass flow passage that bypasses the metering orifice, and a bypass check valve is arranged internally of the valve body in the bypass flow passage. The bypass check valve is configured to open at least partially in response to operating fluid flowing in a reverse flow bypass mode in which activation of the bypass check valve opens the bypass flow passage to permit operating fluid to bypass the metering orifice in the reverse bypass mode.
