Abstract

一种成套使用的化油器泵膜,涉及一种汽油机化油器配件,是用尼龙、聚乙烯、聚脂材料制成的浸油后不易变形的泵膜(A)与弹性好的泵膜(B)重叠构成的复合式泵膜,泵膜(A)上开有止回舌头、气孔、定位销孔以及装配孔,其泵油部位上有一圆孔;与泵膜(A)配套使用的泵膜(B)采用橡胶薄膜等弹性好的材料制成,其上开有分别与泵膜(A)上的气孔、定位销孔以及装配孔位置对应的气孔、定位销孔和装配孔,其与泵膜(A)的止回舌头对应的位置开有两个比止回舌头略大的方孔或同样的止回舌头。该化油器泵膜止回效果好,弹性好、张弛的幅度大,泵油好;使配装此种泵膜化油器的汽油机在使用过程中,化油器的供油好,可以明显缩短起动时间,怠速稳定。
A kit applied carburetor pumping diaphragm, which relates to a petrol engine carburetor accessory that is a compound pumping diaphragm overlapped by a pumping diaphragm (A) made by nylon, polyethylene and polyester material which is hard to deform after gumming and a pumping diaphragm (B) with good elasticity, a non-return tongue, an air hole, a positioning pin hole and an assembling hole are provided on the pumping diaphragm (A), and a round hole is also provided on the portion where the pumping diaphragm (A) pumps oil, the pumping diaphragm (B) which is mated used with the pumping diaphragm (A) is made of good elastic materials such as rubber diaphragm and the like, an air hole, a positioning pin hole and an assembling hole are arranged on the pumping diaphragm (B) at the positions corresponded with the air hole, the positioning pin hole and the assembling hole on the pumping diaphragm (A), two square holes that are a little bigger than the non-return tongue or a same non-return tongue are provided on the pumping diaphragm (B) at the position corresponded with the non-return tongue on the pumping diaphragm (A). The carburetor pumping diaphragm reaches good non-return effect, great flexibility, large amplitude of relaxation, and good oil pumping effect. During the operation of the engine with the carburetor pumping diaphragm, the carburetor provides good oil supplying effect, and the engine with the carburetor pumping diaphragm is capable of shorten the time consumed on starting up, and stabilising the idling.
