    Abstract: An oil level sensor cover according to an embodiment of the present disclosure may be mounted below an engine oil pan to protect an oil level sensor that measures an oil level. The oil level sensor cover may be formed with plates of predetermined sizes, including an upper surface and a lower surface opposite to the upper surface, wherein a plurality of seating portions and a plurality of hook are formed on the upper surface. An engine according to another embodiment of the present disclosure comprises the above-described oil level sensor cover according to an embodiment of the present disclosure, an engine oil fan, and an oil level sensor mounted below the engine oil fan to measure the oil level. The oil level sensor cover can be separated from or coupled to the oil level sensor without the use of a separate tool.

    Abstract: A method of detecting degradation of a lubricant in a bearing of an electrical machine, including: a) obtaining a first outer bearing ring temperature, b) changing the speed of the electrical machine, c) obtaining a second outer bearing ring temperature when the speed has changed, d) determining a thermal response value of the outer bearing ring based on the first outer bearing ring temperature and the second outer bearing ring temperature, e) comparing the thermal response value with a reference thermal response value for the same speed change as in step b), and f) in case the thermal response value differs from the reference thermal response value, concluding that the performance of the lubricant has degraded.

    Abstract: In a valve member, supply and discharge apertures of fluid are formed at a body having a fluid space E. A one electrode Da including a contact T is provided at an aperture edge of the supply aperture and/or a peripheral part of an aperture edge of the body. The body includes another electrode Db, and stores a valve member made of a conductor and opening and closing the supply aperture, and a coil spring made of a conductor and urges the valve member. A guide member made of a conductor is attached onto the valve member. The guide member is formed to secure a flow path of the fluid from the supply aperture to the discharge aperture while being slidable in the fluid space E, has a reception surface facing one end face of the fluid space E while receiving the fluid from the supply aperture.

    Abstract: A system for distributing semisolid lubricant, including a semisolid lubricant tank and a high pressure pumping system that intermittently feeds, during a lubrication cycle, at least one first duct, the at least one first duct feeding a plurality of distributors adapted to sort the semisolid lubricant to a plurality of users; a controlled suction/delivery device, fluidly associated with the first duct, for controlled suction/delivery of a part of the semisolid lubricant conveyed by the first duct. The controlled suction/delivery device configured to suck a volume of semisolid lubricant from the first duct during a step of inactivity of the pumping system on the first duct, and to introduce the previously suctioned semisolid lubricant in the first duct during a step of activity of the pumping system on the first duct.
