In the piston type three-way valve of the present invention, when the piston rod 14 moves leftwards (here, "left" and "left and right" mentioned in the specification are illustrated by the drawings of the specification), the fluid in the space formed by the left end surface of the first protrusion 7, the valve body 1 and the cover plate 23 is compressed, at this time, the high-pressure fluid is applied to the plug 1302 of the one-way valve 13, the plug 1302 compresses the first elastic member 1303 in the one-way valve 13, and the high-pressure fluid is discharged through the channel between the plug 1302 and the housing 1301, so that the pressure of the fluid in the space formed by the left end surface of the first protrusion 7, the valve body 1 and the cover plate 23 is reduced, and the movement resistance of the piston rod 14 is reduced. High pressure fluid is expelled through the passage between plug 1302 and housing 1301, which is particularly important for solid fluids where the piston rod 14 cannot operate if the solid fluid accumulates without being expelled through check valve 13. The case where the piston rod 14 is moved rightward coincides with the case where the piston rod 14 is moved leftward. The piston type three-way valve is simple and practical in structure, simple to install and maintain and convenient to operate, and reliability of the valve is effectively improved.
It should be noted that, in the embodiments, the "three-way valve", "piston type three-way valve" and "valve" are all referred to as the piston type three-way valve of the present invention.
