SPOOL VALVE Russian patent published in 2019 - IPC F16K11/65 

FIELD: machine building.

SUBSTANCE: present invention relates to slide valve wherein flow channels between multiple openings are opened and closed by slide sliding in valve opening. Section of valve hole 8 has an elongated shape having a long axis X, oriented in the direction of the height of housing 7, and a short axis Y oriented in the direction of the width of housing 7, and has left and right sidewalls 8a, 8a extending linearly in the long axis direction and parallel to each other, a first end wall 8b of the opening which connects one ends of the left and right sidewalls 8a, 8a, and the second end wall 8c of the hole that connects the other ends of the left and right side walls 8a, 8a of the hole and the section of seating areas 11–13 of slide valve 10 has an elongated shape having a long axis X oriented in the direction of the height of housing 7, and a short axis Y oriented in the width direction of housing 7 and has left and right seating side walls 25a, 25a extending linearly in the direction of the long axis X and parallel to each other, first mounting end wall 25b, which connects one ends of left and right mounting sidewalls 25a, 25a, and a second mounting end wall 25c, which connects other ends of the left and right sidewalls.

EFFECT: technical task of present invention is to increase cross-section area around sections of shaft spool by increasing the area of section of valve hole and slide valve without increasing width of housing compared to known spool valve, that is creation of slide valve, having compact dimensions and rational structure of structure.
