用于汽车空调或热泵内的涡旋压缩机的控制流量调节阀
摘要：
本发明涉及尤其用于汽车空调或热泵内的涡旋压缩机(7)的控制流量调节阀(1)，至少由外壳(8)、封闭部件(9)及流体连接部(2)、流体连接部(3)、流体连接部(4)形成，上述流体连接部(2)、流体连接部(3)、流体连接部(4)用于具有分配给多个流体连接部的上述封闭部件的有效面积(effective area)的逆压(Pb)、高压(Pd)以及吸入压力(Ps)的控制流量，上述控制流量调节阀的特征在于，形成有具有附加分配的封闭部件(9)的有效面积的周边压力(ATM)的流体连接部(5)，从被施加到封闭部件(9)的压力(Pd)、压力(Pb)、压力(Ps)、压力(ATM)获取的力量作用于上述封闭部件(9)，以使从高压(Pd)到吸入压力(Ps)的控制流量以形成逆压(Pb)的方式流动，在此情况下，上述周边压力(ATM)作用于上述封闭部件(9)，相对于具有高压(Pd)、逆压(Pb)及吸入压力(Ps)的其他腔体以流体密封的方式形成。
摘要（英）：

The present invention relates to a control flowrate regulating valve (1) specifically for a scroll compressor (7) inside a vehicle air conditioner or a heat pump, the valve at least comprising: a housing (8); a closing member (9); and fluid connection parts (2, 3, 4) for a control flowrate of back pressure (Pb), high pressure (Pd) and suction pressure (Ps), the fluid connection parts having effective areas, of the closing member, assigned to the fluid connection parts. The control flowrate regulating valve has a fluid connection part (5), for peripheral pressure (ATM), having an additionally assigned effective area of the closing member (9), and is formed in a fluid-sealing manner for other chambers having high pressure (Pd), back pressure (Pb), and suction pressure (Ps), such that the force, obtained from the pressures (Pd, Pb, Ps, ATM) applied to the closing member (9), is applied to the closing member (9) so as to allow the control flowrate, which moves from the high pressure (Pd) to the suction pressure (Ps), to flow in a manner of forming the back pressure (Pb), wherein the peripheral pressure (ATM) is applied to the closing member (9).
