スリップ防止弁。(1) In a hydrostatic transmission device that constitutes a closed circuit consisting of a variable displacement pump and a fixed displacement motor in the drum drive device of a truck mixer, etc., a pilot operated check valve is installed on the high pressure side when the drum is reversed. The check valve's pilot boat is connected to the high-pressure side circuit during normal rotation of the drum, and when the pump is temporarily placed in neutral during discharge of ready-mixed concrete and an attempt is made to stop the drum, the problem occurs due to an uneven load inside the drum. In a circuit configuration in which the pilot operated check valve attempts to avoid at least the elements caused by the pump leakage by the pilot operated check valve, the slight rotational action of the hydraulic motor caused by leakage of the hydraulic motor and pump at the pressure An anti-slip valve characterized by having a dual structure of a large-diameter valve body that allows a large flow rate to pass through, and a small-diameter valve body that allows a small volume of flow volume to pass through.
