It consists of a hydraulic control device, and if chips or foreign objects such as iron powder get mixed into the hydraulic fluid, the various hydraulic valves that make up the hydraulic control device will become stuck in each part of the hydraulic control device where the hydraulic fluid circulates. This may cause malfunction of various hydraulic valves.

The oil strainer is used to remove chips and foreign objects such as iron powder from the hydraulic oil that has come up, so chips and foreign objects such as iron powder inside the hydraulic control device will not be removed unless they are moved into the oil pan. There was a risk that chips such as iron filings and foreign matter in the control device would get caught in the various hydraulic valves that make up the hydraulic control device, causing the hydraulic valves to become stuck and causing malfunction of the various hydraulic valves.

異常をきたすことになる。 In particular, in a fluid governor pressure generator used to supply governor pressure according to vehicle speed,
a governor body in which a fluid governor pressure generating device is fixed to a rotating shaft; a governor valve that is disposed in a hollow portion of the governor body so as to be slidable in the radial direction and is slid by centrifugal force; It is composed of an input path and an output path that are communicated through a gap between an inner wall and an outer wall of the governor valve, and adjusts the hydraulic pressure supplied from the input path to a hydraulic pressure corresponding to the rotation speed of the rotating shaft. Since the centrifugal force is generated in the output path, chips and foreign matter such as iron powder in the oil path are likely to be caught between the governor body and the governor valve, and the governor valve is likely to become stuck. If the governor valve becomes stuck, the governor pressure that corresponds to the vehicle speed will no longer be generated, resulting in an abnormality in the shift control of the automatic transmission.

果を有する。<Operations and Effects of the Invention> According to the present invention, at least one of the input path and the output path provided in the governor body fixed to the rotating shaft of the fluid governor pressure generating device has a branched line from the input path or the output path. A branch path is formed that protrudes and opens in a direction away from the rotation center of the rotation shaft from the branch portion, and the branch path is formed in a stepped shape so as to have a diameter larger than the diameter of the input path or the output path. Since a concave magnet is arranged at the opening of the path so as to close the opening,
Due to the centrifugal force exerted when the governor body rotates with the rotating shaft, fine chips and foreign matter that could not be removed by the oil strainer installed in the oil pan are removed by the large-diameter branch. This prevents chips and foreign matter from accumulating in the passageway and introducing them into the gap between the valve element of the governor pressure generator and the governor body, eliminating the stickiness between the valve element and the governor body, and the governor pressure generator is constantly operating. This has the effect of generating normal governor pressure.

ナ圧を発生するようになるという効果を有する。 In addition, since a concave magnet is disposed at the opening of the branch passage so as to close the opening, even when the governor body is not rotating, the magnetic force of the magnet can remove fine chips and debris. Since foreign matter accumulates in the branch passage formed with a large diameter, even when the governor body begins to rotate, chips and foreign matter are not introduced into the gap between the valve body of the governor pressure generating device and the governor body, and the connection between the valve body and the governor body is prevented. This has the effect that the governor pressure generating device can now generate normal governor pressure since there is no longer any stickiness between the two.
