Abstract:
An expansion valve body, comprising:a prism-shaped valve body member extending along a centrally-disposed longitudinal axis and having a first wall and an opposite second wall, the first and second walls extending longitudinally and laterally, a third wall and an opposite fourth wall, the third and fourth walls extending longitudinally and transversely and connected perpendicularly at respective longitudinal edges to the first and second walls to define in cross-section a rectangular configuration and a pair of opposite end walls extending laterally and transversely and connected at respective lateral and transverse edges to the first, second, third and fourth walls to define the prism shape, the valve body member including a gas phase refrigerant passage and a liquid phase refrigerant passage extending through and between the first and third walls to form a gas phase refrigerant opening and a liquid phase refrigerant opening in each one of the first and third walls, respective ones of the gas phase refrigerant openings and the liquid phase refrigerant openings being longitudinally disposed apart from one another, a bore extending longitudinally through and between the pair of opposite end walls at a position offset from the centrally-disposed longitudinal axis away from the first wall and closer to the second wall, the bore being in fluid communication with and causing fluid communication between the gas phase refrigerant passage and the liquid phase refrigerant passage and a pair of penetrating holes extending linearly through and between the third and fourth walls with the bore positioned therebetween, the pair of penetrating holes being in fluid isolation from the gas phase refrigerant passage, the liquid phase refrigerant passage and the bore.
