PDHとは 意味・読み方・使い方

Meanwhile, when the pressure Pdl becomes higher the pressure Pdh while closing the first valve portion, a second valve portion is opened when the differential pressure (Pdl-Pdh) becomes more than the valve opening differential pressure ΔP2 to permit the back-flow of the discharged refrigerant while controlling it under a low flow rate.例文帳に追加

一方、このように第１の弁部が閉弁した状態において圧力Ｐｄｌが圧力Ｐｄｈよりも高くなった場合、その差圧（Ｐｄｌ−Ｐｄｈ）が開弁差圧ΔＰ２よりも大きくなると第２の弁部が開弁し、吐出冷媒の逆流を低流量に規制しつつも許容する。 - 特許庁

A pressure sensitive member 54 is displaced corresponding to differential pressures PdH-PdL between two pressure monitoring points P1, P2 set in a cooling medium circulation circuit, and the displacement is reflected by the positioning of the valve element 43 so that the discharge displacement of the compressor can be changed to the side of cancelling the variation of the differential pressures PdH-PdL.例文帳に追加

感圧部材５４は、冷媒循環回路に設定された二つの圧力監視点Ｐ１，Ｐ２の差圧ＰｄＨ−ＰｄＬに応じて変位し、この変位は同差圧ＰｄＨ−ＰｄＬの変動を打ち消す側に圧縮機の吐出容量が変更されるように、弁体４３の位置決めに反映される。 - 特許庁

A pressure- sensitive member 54 is displaced according to a differential pressure PdH-PdL between two pressure monitoring points P1 and P2 set in a refrigerant circulation circuit, with this displacement being reflected on positioning of the valve element part 43 so that the displacement of the compressor is varied to cancel out fluctuation of the differential pressure PdH-PdL.例文帳に追加

A pressure-sensitive member 54 is displaced in conformity with a differential pressure PdH-PdL between two pressure monitoring points P1 and P2 set in a refrigerant circulating circuit and this displacement is reflected on positioning of the valve disk part 43 so that the discharge capacity of the compressor is changed to the side of canceling fluctuation of the differential pressure PdH-PdL.例文帳に追加

感圧部材５４は、冷媒循環回路に設定された二つの圧力監視点Ｐ１，Ｐ２間の差圧ＰｄＨ−ＰｄＬに応じて変位し、この変位は同差圧ＰｄＨ−ＰｄＬの変動を打ち消す側に圧縮機の吐出容量が変更されるように、弁体部４３の位置決めに反映される。 - 特許庁

Displacement of the member 54, based on the variation of the pressure difference PdH-PdL between the two chambers 55 and 56, is reflected on the degree of opening of a gas supply passage 28, so that the discharge capacity of the compressor is changed to the side to cancel the variations in the pressure difference PdH-PdL.例文帳に追加

そして、両室５５，５６間の圧力差ＰｄＨ−ＰｄＬの変動に基づく感圧部材５４の変位は、同圧力差ＰｄＨ−ＰｄＬの変動を打ち消す側に容量可変型圧縮機の吐出容量が変更されるように、給気通路２８の開度に反映される。 - 特許庁

In this compressor, a first valve portion of the discharge valve 7 is closed to prevent leakage and back-flow of a discharged refrigerant when differential pressure (Pdh-Pdl) between a pressure Pdh and a pressure Pdl in transition to a minimum capacity operation, becomes less than a valve opening differential pressure ΔP1.例文帳に追加

圧縮機においては、最小容量運転移行時に圧力Ｐｄｈと圧力Ｐｄｌとの差圧（Ｐｄｈ−Ｐｄｌ）が開弁差圧ΔＰ１よりも小さくなると、吐出弁７の第１の弁部が閉弁し、吐出冷媒の漏洩および逆流を防止する。 - 特許庁

The pressure sensitive member 54 is displaced according to differential pressure PdH-PdL between the two pressure monitoring points P1 and P2, and this displacement is reflected on positioning of the valve element part 43 so that delivery capacity of the compressor is changed to the side for offsetting a fluctuation in the differential pressure PdH-PdL.例文帳に追加

感圧部材５４は、二つの圧力監視点Ｐ１，Ｐ２間の差圧ＰｄＨ−ＰｄＬに応じて変位し、この変位は同差圧ＰｄＨ−ＰｄＬの変動を打ち消す側に圧縮機の吐出容量が変更されるように、弁体部４３の位置決めに反映される。 - 特許庁

A lock position detecting circuit 30 counts the Low period (PDL) of a PD signal and the High period (PDH) of the PD signal generated at a phase comparing part 23 to generate an SRT shift signal having the pulse width of (PDL-PDH)/2.例文帳に追加

ロック位置検出回路３０は、位相比較部２３において生成されるＰＤ信号のＬｏｗ期間（ＰＤＬ）、およびＰＤ信号のＨｉｇｈ期間（ＰＤＨ）をカウントし、（ＰＤＬ−ＰＤＨ）／２のパルス幅を有するＳＲＴシフト信号を生成する。 - 特許庁
