WIPO Patent Application WO/2016/131391

A1

A proportional valve body, proportional valve and manufacturing method for the proportional valve body. The proportional valve body (100) comprises a body (1) extending in an axial direction, and the body (1) is provided with a first cavity (131) and a second cavity (132) penetrating therethrough in the axial direction and isolated from each other. The body (1) is further provided with a first through hole (141) penetrating through an outer wall of the body, being in communication with the first cavity (131) and isolated from the second cavity (132). The first cavity (131) and the second cavity (132) of the proportional valve body (100) penetrates therethrough in the axial direction of the body (1), so that the general structure of the proportional valve body (100) can be obtained by means of extrusion molding. Extrusion molding has the advantages of easy operation, high productivity, and high raw material utilization ratio, and the proportional valve body (100) obtained by means of extrusion molding has a favorable structural and mechanical performance.
