Abstract

PURPOSE: To promote the capacity of a pump by opening a passage connected to an oil reservoir in a bypass passage and providing a thermally responsive device in this passage for opening the passage when the temperature of a working oil is excessively raised.
CONSTITUTION: A passage 60 connected to an oil reservoir is opened in a bypass passage 26 connecting between a valve chamber 41 and a suction passage, and a thermally responsive device 61 is provided in this passage 60. When the temperature of the working oil is abnormally raised by the continuous relief operation of a discharge-regulating valve 40, the passage 60 is opened to return a part of the working oil from the valve chamber 41 into the oil reservoir, and new cool working oil in the reservoir is conducted into the suction passage as pressure in lowered in the bypass passage 26 by virtue of that returned working oil. In this construction, the working oil circulating in a pump can be prevented from the sudden rising of the temperature. Consequently, the pump is prevented from the seizure of a sliding member and deteriorations of a sealing member and the working oil, and improved in its performance.
