喷油泵接头的清洁装置

Cleaning device of fuel injection pump connector

Abstract

The invention relates to the technical field of fuel injection pumps, in particular to a cleaning device of a fuel injection pump connector. The cleaning device comprises a connector body, a fuel inlet and a fuel outlet. The fuel inlet is located in the upper portion of the connector body, the fuel outlet is located in the lower portion of the connector body, and the connector body is formed by a sleeve and a fuel pipe. A bush is a cylindrical elastomer and is arranged in the fuel pipe and attached to the inner wall of the fuel pipe. The sleeve is inserted in the top of the fuel pipe and is in threaded connection with the fuel pipe. The bottom of the sleeve is inserted in a cavity on the top of the bush. According to the cleaning device, the bush, namely the cylindrical elastomer, is arranged in the fuel pipe, the sleeve is used for sealing the bush to enable the bush to be tightly attached to the inner wall of the fuel pipe, when fuel enters the fuel pipe, the contact between the fuel and the inner wall of the fuel pipe can be avoided, the bush can adsorb impurities so that cleanliness of the fuel can be improved, breakdowns caused by the impurities of the fuel are avoided, and working reliability of the fuel injection pump is improved.
本发明涉及喷油泵的技术领域,尤其是一种喷油泵接头的清洁装置,包括接头体、进油口和出油口,所述进油口位于接头体的上部,所述出油口位于接头体的下部,所述接头体由套管和油管组成,油管内设有衬套且为筒状弹性体,贴合在油管的内壁上,所述套管插在油管的顶部,与油管螺纹连接,所述套管底部插在衬套顶部的空腔内。本发明在油管内设有筒状弹性体的衬套,且用套管封住衬套使衬套能紧密贴合在油管的内壁上,当油料进入到油管时,可杜绝油料与油管内壁的接触并且衬套能吸附杂质从而提高油料的清洁度,避免发生因油料杂质而引起的故障,提高了喷油泵工作的可靠性。
