Description
【0007】
また、流量を調整するためにポンプより送り出されるエアー等の流路中に流量調整器を設けることがある。つまり出口15の気体通路やこれに接続するエアー供給管内に流量制限体を設けたものであって、これによって低流量の空気供給を流量、圧力の変動のほとんどない状態にて行なうようにしたもので、ここで用いられている流量制限体は、図8(A)に示す通り、螺旋溝31を有するものである。これをポンプの出口25内等の流路中に圧入等の方法で挿入したもので、流量制限体30の外周部つまりねじのねじ山部分に相当する径の最も大きい部分32が出口の内壁面に密着されている。そして螺旋状の溝31を通って気体は排出される。即ちこの流量制限体30の溝31であるねじの谷の部分が流路をなす。また流量制限体として、図8(B)に示すような構成のものつまり円柱形の本体33の外周面に軸方向に伸びる直線溝34を形成したもので、この直線溝34が流路をなすものも考えられる。[0007]
Moreover, in order to adjust the flow rate, a flow rate adjuster may be provided in a flow path of air or the like delivered from the pump. That is, a flow restrictor is provided in the gas passage of the outlet 15 and the air supply pipe connected thereto, whereby low-flow air supply is performed with little fluctuation of the flow rate and pressure. The flow restrictor used here is one having a spiral groove 31 as shown in FIG. 8 (A). This is inserted into a flow path such as the inside of the outlet 25 of the pump by a method such as press fitting , and the portion 32 having the largest diameter corresponding to the outer peripheral portion of the flow restrictor 30, ie, the screw thread portion of the screw is the inner wall surface of the outlet It is in close contact with The gas is then evacuated through the spiral groove 31. That is, the valley portion of the screw which is the groove 31 of the flow rate limiting body 30 forms a flow path. Further, as the flow rate limiting member, a device as shown in FIG. 8B, that is, a linear groove 34 extending in the axial direction is formed on the outer peripheral surface of the cylindrical main body 33. Things are also conceivable.
