プ装置のエンスト防止機構。 The oil discharged from the oil pump is sequentially transferred to the spool chamber.
In a power steering oil pump device provided with a flow control valve for supplying oil to a power steering device through an orifice and a discharge chamber, the oil pump device comprises first and second spool chambers communicating with the spool chamber and the discharge chamber, respectively; a spool chamber forming a discharge port for returning oil to the oil pump; a compression spring slidably fitted into the spool chamber and housed in the second spool chamber; and a hydraulic pressure in the second spool chamber. An engine stall prevention mechanism for an oil pump device for power steering, comprising: an engine stall prevention spool that is energized by the cooperative action of the engine stall prevention spool to open and close the discharge port of the spool chamber.
