An oil chamber wall arrangement is described as comprising: a chamber wall surrounding a rotor; a plurality of apertures defining through-holes for a flow of oil through the chamber wall, the apertures being defined by a pair of axially separated opposing walls and a pair of circumferentially opposing walls wherein the circumferentially opposing walls are separated by a midline which is radial to the rotational axis of the rotor and at least one of the pair of circumferentially opposing walls is not parallel to the radial midline.

A system is disclosed. The system includes a processing station for processing at least one of a tire and a wheel prior to joining the tire and the wheel for forming a tire-wheel assembly. The processing station includes one of a tire lubricating sub-station and a wheel lubricating sub-station. A lubrication conditioning system is fluidly-coupled to the processing station. The lubrication conditioning system includes: a lubricant reservoir, a lubricant temperature modifier arranged at least proximate to the lubricant reservoir, a lubricant temperature sensor arranged within a cavity formed by the lubricant reservoir and a controller communicatively-coupled to both of the lubricant temperature modifier and the lubricant temperature sensor.

A hydraulic fluid de-aeration device for a hydraulically actuated variable valve actuation system is provided. The device includes a bridge and a de-aeration chamber having an upper chamber, a lower chamber, and a central axis. A vent pipe is arranged along the central axis of the de-aeration chamber and can include at least one vent hole. The bridge is arranged such that hydraulic fluid flowing from the bridge is directed towards an outer wall of a top portion of the lower chamber. The device includes a cover that integrates the upper chamber with a vent hole for air that is expelled from the hydraulic fluid. An optional gasket or plate configured with at least one vent hole can be arranged between the upper and lower chamber. The vent pipe can be arranged within the cover and extend through the upper chamber to the lower chamber.

A method of and an arrangement for improving the lubrication system of a propulsion device of a marine vessel are specifically applicable in removing water from the lubrication oil of various types of thrusters. An inert gas is arranged from an inert gas source to flow through a gas cavity in the lubrication system for flushing moist gas from the cavity.

A gas turbine engine comprises a fan drive turbine for driving a gear reduction. The gear reduction drives a fan rotor. A lubrication system supplies oil to the gear reduction. The lubrication system includes a lubricant pump supplying a mixed air and oil to a deaerator inlet. The deaerator includes a separator that for separating oil, and delivering separated air to an air outlet, and for delivering separated oil back into an oil tank. The separator includes a member having lubricant flow paths on both of two opposed sides. A method of designing a gas turbine engine is also disclosed.

In a vehicle having a microscopic dynamics friction mechanism formed of at least two parts and charged to a positive potential due to traveling, a lubricant in which first additive fine particles made of a resin that generates a negative potential are uniformly mixed with an electrically insulating base oil is disposed in a clearance between members of the friction mechanism. While the first additive fine particles are in frictional contact with the member, neutralization and elimination of the positive potential of the member are started. The first additive fine particles are attracted by a Coulomb force to the positive potential of the surface of the member other than a frictional contact part of the member when floating in the electrically insulating base oil and moving and circulating. The neutralization and elimination of the positive potential of the member are continued.
