Abstract
An on-vehicle oil sensor includes an enclosure and a detecting unit. The enclosure includes: an enclosure inner space provided inside the enclosure and configured to allow oil to enter the enclosure inner space; and a plurality of oil paths provided in the enclosure and connecting an exterior of the enclosure to the enclosure inner space. The detecting unit is configured to detect at least one of pressure of oil in the enclosure inner space and temperature of oil in the enclosure inner space.
Claims5
An on-vehicle oil sensor comprising:
- an enclosure including:
- an enclosure main body component having an enclosure inner space provided therein and configured to allow oil to enter the enclosure inner space;
- and an oil path forming component having a plurality of oil paths communicating with the enclosure inner space and connecting an exterior of the enclosure to the enclosure inner space, the enclosure main body component and the oil path forming component extending in an axial direction and the plurality of oil paths extending in said axial direction;
- and
- a detecting unit provided in the enclosure inner space and configured to detect at least one of pressure of oil in the enclosure inner space and temperature of oil in the enclosure inner space,
- wherein when the on-vehicle oil sensor is installed in a mounting member having oil flowing therein, the oil flows across the oil path forming component in a direction perpendicular to the axial direction, flows along at least one of the plurality of oil paths in said axial direction into said enclosure inner space and then exits through at least one of the other plurality of oil paths.
