Title:
EXPANSION VALVE OF REFRIGERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2005/075903
Kind Code:
A1
Abstract:
An expansion valve capable of reducing refrigerant passing noise by miniaturizing air bubbles in a gas-liquid two-phase refrigerant flowing in the expansion valve without decreasing the adjusting range of the opening adjusting function of an orifice and a refrigerating apparatus using the expansion valve. The expansion valve comprises a valve body (1), two ports (2) and (3) formed, as the inlet and outlet of the refrigerant, in the valve body (1), a refrigerant passage (4) formed between the both ports (2) and (3) in the valve body (1), the orifice (5) formed in the refrigerant passage (4), and a turbulent part (6) causing turbulence in the flow of the refrigerant formed in the refrigerant passage (4) on the upstream side of the orifice (5).
