Description

一种双向油压调节装置
所属技术领域
本发明涉及油压调节器领域,提供了一种双向油压调节装置。
背景技术
 燃油压力调节器,它是燃油***内部的燃油压力调节部分,受***油压与进气支管压力(负压)的控制。它的作用是要自动保持整个油压***的燃油压力为一定值,使供油总管内油压与进气支管压力之差为一定恒值(一般为250~300kPa)。当***油压与进气支管压力差发生变化时,燃油压力调节器会因应***油压与进气支管压力差的变化作相应的变化,以便保持***内的油压稳定。现有的回油阀采用的多是单一的压力调节单元。
发明内容
本发明的目的在于提供一种调节能力更加灵敏、稳定的一种双向油压调节装置。
本发明为实现上述目的采用以下技术方案:
一种双向油压调节装置,包括进油口、回油口、燃油室和由膜片、回油阀、真空管、空气室、弹簧组成的压力调节单元,其特征在于:在空气室两端设置有对称的2个压力调节单元。
本发明的有益效果:
本发明相对于现有的单压力调节的油压调节器而言采用对称的压力调节单元,使得其调节能力更加敏捷、稳定。
附图说明
图1为本发明的结构原理图;
图1中1进油口、2回油口、3膜片、4回油阀、5真空管、6空气室、7弹簧、8燃油室。
具体实施方式
一种双向油压调节装置,包括进油口、回油口、燃油室和由膜片、回油阀、真空管、空气室、弹簧组成的压力调节单元,其特征在于:在空气室两端设置有对称的2个压力调节单元。
当燃油压力过大的时候,2个回油阀同时打开,然后经过回油口流入回油口,从而调节燃油压力。
