Connect between the outer wall 24a and the inwall 12a of valve body 12 of 24 and with valve chamber 14, side annular flow outside
In road 48, the fluid of flowing refluxes to valve chamber 14 via vertical stream 80.
I.e., in this case, vertical stream 80 is with deposition portion 82 opening towards outside annular flow path 48
Mode is formed, and in deposition portion 82, in side annular flow path 48, the fluid of flowing collaborates and flow velocity each other outside
Reduce.
Therefore, the outside that the fluid of flowing collaborates each other and flow velocity reduces in side annular flow path 48 outside is ring-type
In the deposition portion 82 of stream 48, flow velocity extremely reduces.
Therefore, continue from the first tube parts 16 court as inlet attack at fluid according to Bernoulli's theorem
In the valve chamber 14 as the second tube parts 18 flowing of outlet connection and the outside that extremely reduces of flow velocity
Pressure differential will be produced between the deposition portion 82 of annular flow path 48.That is, the deposition portion of outside annular flow path 48
82 sides are high pressure, and valve chamber 14 side is low pressure, thus produce from outside annular flow path 48 via vertical stream 80
And to the flowing slowly of valve chamber 14 backflow.
Thus, the fluid such as cold-producing medium containing the foreign body such as mud, metal powder will not be stranded in rotor chamber 28,
And discharge in valve chamber 14, thus the foreign bodies such as mud contained in fluid, metal powder will not invade feeding
Leading screw portion (the external screw thread 54a of the external thread part 54 of the armature spindle 52 and female thread 50a of interior threaded part 50
Between), without making the sliding of threaded portion deteriorate due to nip, injured etc., and then can be not easy to produce
The lively work making the most smoothly and reliably to carry out valve.
