Claims

[Scope of utility model registration request]

In a flow path switching valve, the openings at one end are alternately opposed to one of a pair of cylinders having openings communicating with a hopper into which fresh concrete is charged, by swinging. The opening at one end faces one of the cylinders by the swinging of the flow path switching valve, and the opening at the other end faces substantially upward, and the opening at the other end faces the wall. A flow path switching valve for a concrete pump, characterized by comprising a pair of metal guide members in which holes of appropriate size are formed. −
