Abstract:
[Problem] To provide a relief device for an oil circuit of an engine provided with an oil pressure relief valve and a temperature-sensitive relief valve, with which it is possible for oil to be relieved (expelled) at the intended pressure regardless of the oil temperature, and with which it is possible to simplify the configuration. [Solution] The relief device comprises an oil pump (9), an upstream channel (61) provided from a discharge side of the oil pump (9) to an engine (E), an oil pressure relief valve (A) for relieving oil due to the valve body being moved by oil pressure, and a temperature-sensitive relief valve (B) for relieving oil by sensing the oil temperature and continuously opening and closing. The oil pressure relief valve (A) and the temperature-sensitive relief valve (B) are arranged in parallel in the upstream channel (61).
