PURPOSE:To prevent brake oil from vapor lock with a simple constitution by providing in parallel a portion of a brake tube piped in an engine room and a portion of the low pressure side pipe of a cooler to be covered with a heat screening plate. CONSTITUTION:The low pressure side pipe 8 of a cooler is piped in parallel to and adjacent a brake tube 4 arranged in an engine room 1, and the surfaces of brake tube 4 and low pressure side pipe 8 are covered with a heat screening plate 9. Thus, low temperature refrigerant passing through an evaporator in cooler cycle passes by the low pressure side pipe 8 to lower the atmospheric temperature. Thus, brake oil flowing in the brake tube 4 is cooled to suppress the rise of temperature and prevent vapor lock. |
