FIELD: engines and pumps.
SUBSTANCE: proposed flow channels switch 30 is arranged in hydraulic circuit to switch over oil feed channels depending upon oil temperature. Said switch 30 comprises: thermal valve case 31 that includes multiple channels communicated with ambient medium and cylinder 36 that displaces in thermal valve case to switch over oil feed channels depending upon oil temperature. Cylinder 36 is moved to preset position and secured by outer element 139 on feeding oil in hydraulic circuit at low temperature.
EFFECT: higher operating performances in feeding low-temperature fluid into circuit to be connected at high temperature of fluid.
