Annotation:
The article presents a description of the spool valve, which can be used in oil production by the mechanized method, in particular, sucker-rod pumps to increase the overhaul period of the sucker rod pumping unit. When using the proposed device, there occurred increase of the sucker-rod pump repair period by reducing the impact loads when the valve is being closed as well as reducing the contact stresses on the conical surface inside the housing due to the redistribution of the axial load on the elastic element on the rod.
