This paper concerns a newly designed water hydraulic actuator to make reciprocating linear motion without any directional control valves outside. It works with only supply of low pressure water, such as from tap water network. The object of this paper is to introduce the idea of construction and working principle of the actuator and to present some experimental results gained by prototypes. Two different prototypes, with a short stroke (approx. 20 mm) and a long stroke (approx. 200 mm), are

Main piston's displacement, speed, force, and supply flow rate and pressure were measured under steady working conditions. The experimental results are presented and some considerations to improve the characteristics of them are also discussed.
