<p>PURPOSE:To provide a refrigerant piping connection fitting for bending vertically a refrigerant passage in the neighborhood of a connection part, with which the height of the connection fitting is reduced and the manufacturing costs are suppressed. CONSTITUTION:A refrigerant piping connection fitting 1 is composed of a stationary block 4 secured by bolt to an object to be connected 2 and a refrigerant piping 5 threaded through the block 4 and supported, therein the refrigerant piping 5 is bent in L form with a bending radius of approx. zero. The stationary block 4 and refrigerant piping 5 are fixed in the condition that at least the inside bend 10a of this bent part 10 is accommodated in the block 4. This permits suppressing the dimension of the connection surface of the block 4 relative to the refrigerant piping 5, i.e, reducing the height h1 of the connection fitting 1. According to this constitution in which refrigerant passage bent vertically is no more formed in the block 4, but the refrigerant flow is bent vertically by bending the piping 5, it is possible to suppress the manufacturing costs of the refrigerant piping connection fitting 1.</p> |
