  • Patent number: 9937506
    Abstract: A motion guide apparatus cooling nozzle is provided which can gas-cool a motion guide apparatus. Cooling nozzles 1a and 1b of the present invention are mounted on a block 4 of the motion guide apparatus to cool at least one of a guide rail 2 and a block 4 that is assembled to the guide rail 2 via a rolling element 6 in such a manner as to be movable relatively. The cooling nozzles 1a and 1b include an inner passage 18 into which gas is introduced, an opening 12a configured to emit a gas flow introduced into the inner passage 18, a deflection surface 22a that is provided adjacently to the opening 12a to bend the gas flow emitted from the opening 12a, and a guiding surface 32a configured to attract gas outside the cooling nozzles 1a and 1b.
