CN209293874U 一种中置式机油控制阀 有权

一种中置式机油控制阀
摘要：
本实用新型提供一种中置式机油控制阀，包括阀壳体(2)、阀套(4)和阀芯(7)，在阀壳体(2)与阀套(4)之间形成进油油道(8)和第一排油油道(10)，在阀芯(7)上形成阀芯尾翼(71)，阀芯尾翼(71)与阀套(4)之间形成差压槽(12)，在阀套(4)与阀芯(7)之间形成第二排油油道(11)，第一排油油道(10)分别与第二排油油道(11)、差压槽(12)相通。当阀芯相对于阀套轴向移动时，流体在排出、且经过差压槽时所产生的液压推力将作用于阀芯尾翼上，该液压推力有利于缩短阀芯的回位时间，同时，通过第二排油油道来增大排油截面积，减小排油节流损失，具有加快阀芯回位速度、提高排油效率等突出优点。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a central engine oil control valve. The valve comprises a valve shell (2), a valve sleeve (4) and a valve core (7), an oil inlet channel (8) and a first oil discharge channel (10) are formed between the valve shell (2) and the valve sleeve (4); a valve element tail fin (71) is formed on the valve element (7), a differential pressure groove (12) is formed between the valve element tail fin (71) and the valve sleeve (4), a second oil discharging channel (11) is formed between the valve sleeve (4) and the valve element (7), and the first oil discharging channel (10) iscommunicated with the second oil discharging channel (11) and the differential pressure groove (12). When the valve core axially moves relative to the valve sleeve; when fluid is discharged and passesthrough the differential pressure groove, generated hydraulic thrust acts on the valve element tail wing, the hydraulic thrust is beneficial to shortening the return time of the valve element, meanwhile, the oil discharging sectional area is increased through the second oil discharging oil channel, oil discharging throttling losses are reduced, and the outstanding advantages that the return speedof the valve element is increased, and the oil discharging efficiency is improved are achieved.
