包括专用除气路径的液压控制隔膜泵
Abstract:
本发明涉及一种泵，其包括剂量头(1)，剂量头包括：第一部分(2)和第二部分(7)，第二部分中设有液压腔(8)和剂量体(14)，液压腔中填充了流体；剂量体(14)，剂量体(14)包括在液压腔中驱动泵的活塞(13)平移的装置；阀(17)，用于调节在液压腔中的压力；和至少一个除气路径(33；34；36；37)，除气路径在第二部分中延伸；因此形成了所述路径的最低点的路径的第一端部敞开到位于活塞和安装在活塞上的密封件之间的接合处，而形成了所述路径的最高点的路径的第二端部敞开到所述阀的中空体中。
Abstract(English):

The invention relates to a pump comprising a dosage head (1) comprising a first part (2) and a second part (7) in which there is provided a hydraulic chamber (8) which is filled with a fluid and a dosage body (14) comprising means for driving a piston (13) of the pump in translation in the hydraulic chamber, a valve (17) for regularization of pressure in the hydraulic chamber, and at least one degassing path (33, 34, 36, 37) which extends in the second part, such that a first end of the path which forms the lowest point of the said path opens out at a junction between the piston and a seal fitted on the piston, and a second end of the path which forms the highest point of the said path opens out into a hollow body of the said valve.
