| PROBLEM TO BE SOLVED: To provide a method of flow estimation during CPAP treatment. SOLUTION: This method includes a step of measuring turbine speed by Hall-effect sensors. The equivalent pressure p est generated by a turbine corresponding to the measured speed if the flow were zero, is estimated using a predetermined mathematical function. Coincidentally with the speed measurement and pressure estimation, the delivery tube pressure p act is measured by a pressure transducer, and the difference between the two pressures is calculated from p act and p est. This difference represents an estimation of flow f est. The flow estimation value can be linearized by a square root device and then filtered by a combination of low pass and high pass filters to derive a filtered flow estimate value.

| (57)【要約】 質量流体流量コントローラは、コントローラロッド構造体により制御されるバルブを有し、コントローラロッド構造体は、このロッド構造体の運動に従って伸びたり伸びなかったりする金属ダイヤフラムにほぼ枢着されている。 このロッドの作動は加熱されると膨張し、冷却されると収縮するアクチュエータワイヤの膨張および収縮によって生じる。 コントローラを貫通する主要流体流路は直線状であり、平行センサ流体流路を形成するセンサ導管が金属シーラー部材を使用して所定位置に接続されており、シーラー部材は開口部内で主要流体流路まで延び、かかる開口部を貫通する方向に沿って丸くされている。 センサ導管を通過する流れを生じさせるための主要流体流路に沿った圧力低下は、流体流量制限器によって発生される。 この流体流量制限器はコアと、コアに沿ったワイヤとを有する。 ワイヤはセンサ導管の入力および出力接続部の近くでコアとテーパ付き流体流路との間に圧縮されるようになっている。 コアの形状は球形または円形とすることができる。 ブッシングの運動を阻止しながらブッシングの端面に力を加え、端面を変形し、ブッシングの外側壁をパイプ構造体の内側壁に押圧し、ブッシングをパイプ構造体内に固定することにより、主要流体流路を形成するようにパイプ構造体内にバルブシートブッシングが取り付けられる。 コントローラロッド構造体とバルブに対するゲート部材として働くボールとの間の関係では、ボールをコントローラロッド構造体に固定する際に周辺にスリーブを有する細長いステムロッドを使用できる。 コントローラロッド構造体のゲート部材側からボールの位置が離間する距離よりも実質的に長く、コントローラロッド構造体のゲート部材側から離間させて細長いスリーブにステムロッドを固定することにより、ステムロッドを取り付けできる。 | ||||||

| PURPOSE: To obtain the stabilized divided flows by providing a flow-rate measuring flow path so as to connect a first ring-shaped flow path and a second ring- shaped flow path which are in parallel with a main flow path. CONSTITUTION: An inlet port 41 and an outlet port 42 of a flow-rate measuring flow path 40 are provided for a first ring-shaped flow path 56 and a second ring-shaped flow path 58. The action of a straightening element is generated in the ring-shaped flow path. Three projections 54 are elastically in contact with an inner surface 26 of a circular flow path 25 on the upstream side. Fluid is taken into the flow-rate measuring flow path 40 from the ring-shaped flow paths 56 and 58 having the uniform flow-path cross section in the circumferential direction. Therefore, the accurate flow-rate measurement can be performed at a sensor part 14. When the cross-sectional area of the first ring-shaped flow path 56 and the corss-sectional area of the second ring-shaped flow path 58 are adjusted, the stability in the flow-rate measuring flow path 40 can be further increased.

| PURPOSE: To measure a wide range of flow rate with good accuracy by providing a flowmeter of a thermal flow velocity sensor type and a correcting flowmeter in a flow passage, and correcting the measured value of the flowmeter in accordance with the measured value of the correcting flowmeter in a predetermined range of the flow rate. CONSTITUTION: A flowmeter 1 of a thermal flow velocity sensor type and a Karman vortex flowmeter 2 as a correcting flowmeter are provided in a flow passage 11. The measured value of the flowmeter 1 input through a first driving circuit 3 is integrated or multiplied in an integrating/multiplying circuit 6 of a control part 5. Moreover, the measured value of the flowmeter 2 input through a second driving circuit 4 is integrated or multiplied in an integrating/ multiplying circuit 7. A predetermined correction is performed on the basis of the outputs from the circuits 6, 7. At the same time, the circuits 3, 4 are controlled on the basis of the outputs of the circuits 6, 7. An output signal is output from a correcting/outputting circuit 8. In this manner, even when the composition of a gas is changed, the flowmeter of a thermal flow velocity sensor type can be used as a volume flowmeter in a wide range with high accuracy.

| PURPOSE: To obtain a sensor being excellent in mechanical strength and easy to manufacture by constructing flow rate detecting elements of a flow sensor out of tubular bodies having different diameters and by forming a thin-film resistance layer part at least in one of the tubular bodies located inside or outside. CONSTITUTION: Flow rate detecting elements 1b of a flow sensor 1 are constructed of a plurality of concentric tubular bodies 1a having different diameters, a thin-film resistance layer part 7 to be a detecting element surface is formed at least in one of these tubular bodies 1a located inside or outside, and the tubular bodies 1a are disposed so that the axial direction thereof is in accord with the direction of flow of a fluid. In terms of functions, the elements 1b can average a spatial change of the flow, since they are constructed of concentric tubular structure bodies. In terms of a structure, on the other side, they have a large mechanical strength and thus can withstand the severe conditions of the circumstances of vibrations. In terms of manufacture, in addition, the resistance layer 7 can be formed in the tubular body 1a with ease directly or indirectly by a wet-type method and thus the sensor can be mass-produced inexpensively.
