Development of a Heat Actuator Using Liquid-Vapor Phase Change of R134a
Abstract: AbstractLarge volume changes can be produced by liquid-vapor phase change of working fluids which can be used in actuators as the driving power source. The temperature range of working of such actuators depends on the characteristics of the phase change working fluid. In this paper we discuss the concept and design of a heat actuator which uses liquid-vapor phase change of its working fluid for actuation of a piston. The …
