Description

单轴双向柱塞泵
                      技术领域
本实用新型涉及一种柱塞泵，特别是用于喷雾机上的单轴双向柱塞泵。
                      背景技术
现有的用于喷雾机上的水泵，主要是柱塞泵，这种结构的泵结构较为复杂，不易于装配，工作效率不高。
                      技术内容
本实用新型有一泵体，泵体两端各有一泵腔，柱塞经离合变速装置与动力输出端连接，带动柱塞作往复运动，柱塞的两端在泵腔内，泵腔由单向阀分别与泵体上安装的出水管和进水管连通，在出水管一端，连通一调压阀，调压阀上有回水管，出水管的另一端为出水口。本实用新型具有结构简单，压力大，工作效率高，易于制造，耐用，成本低的优点。
                      附图说明
图1是本实用新型的主视图
图2是本实用新型的左视图
                     具体实施例
图中1是本实用新型的泵体，泵体1两端各有一泵腔2，柱塞3安装在泵体1内，柱塞3中间位置有一凹陷，与外部动力输出端连接的离合变速装置连接一偏心轴承4，偏心轴承4在柱塞3凹陷内，通过偏心轴承4的旋转，使柱塞3作往复运动，柱塞3的两端位于泵腔2内，两泵腔2经单向阀分别与安装在泵体1上部的出水管5和下部的进水管6连通，出水管5上与一调压阀7连通，别一端为出水口，调压阀7上有回水管8。
本实用新型的动力为汽油机。
