An assembly for a compartment of a gas turbine engine that includes a housing, a gear, and a baffle disposed about the gear. The baffle includes an upstream portion and a downstream portion. The upstream portion includes an upstream inner wall and an upstream outer wall separated from the gear. The upstream inner wall is positioned between the upstream outer wall and the gear. An upstream flow channel is formed between the upstream inner wall and the upstream outer wall. The downstream portion of the baffle includes a downstream inner wall and a downstream outer wall separated from the gear. The downstream inner wall is positioned between the downstream outer wall and the gear. A downstream flow channel is formed between the downstream outer wall and the downstream inner wall.

An oil cooling system for an aircraft engine, a bypass valve and an associate method of cooling aircraft engine oil are provided. The oil cooling system includes a heat exchanger having an inlet and an outlet. The inlet is in fluid communication with a first oil conduit to receive a first oil flow from the first oil conduit. The heat exchanger facilitates heat transfer from the first oil flow to another fluid. A flow restrictor defining a constriction is operatively disposed to restrict the first oil flow through the heat exchanger. A second oil conduit receives the first oil flow from the heat exchanger. A bypass oil passage provides fluid communication between the first oil conduit and the second oil conduit to allow a second oil flow received from the first oil conduit to flow to the second oil conduit and bypass the heat exchanger.

A health meter with decontamination device for contaminated fluid with a metal casing body with sealable metal lid, inlet port and outlet port, a removable open bucket having a docking lid and a plurality of openings, a hollow tube with an opening connected to an outlet port, a convex reinforcing spacer in the removable open bucket, a compressible decontamination media and a reinforcing seat in the removable open bucket. Contaminated fluid flows into the metal casing body between the removable open bucket and metal casing body through openings in the docking lid into the compressible decontamination media sequentially into the hollow tube and out the outlet port while an inlet and outlet electrode and two sensors in the media communicate with a controller via a network to a plurality of client devices for automatic remote monitoring.

A lubrication system for a frac pump includes a lubrication system housing, a lubricant tank held by the lubrication system housing, a heating device held by the lubrication system housing, a cooling device held by the lubrication system housing, and a filtration device held by the lubrication system housing. The lubrication system housing is configured to be at least one of mounted to a frac pump housing of the frac pump or held within the frac pump housing.

A hydraulic tank for a machine is disclosed herein. The hydraulic tank includes a casing defining an interior space and having an outer surface, an inner surface opposite the inner surface, and a return hydraulic fluid inlet extending through the casing. A first concave member is connected to the inner surface of the casing to form a passage. The passage is positioned and shaped to transport hydraulic fluid from the return hydraulic fluid inlet to another location within the hydraulic tank.

A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.

An air bleeder includes a branch, a lubricant supply conduit, and a return conduit. Lubricant stored in a tank is to be supplied to a valve provided in a machine tool via the lubricant supply conduit. The lubricant supply conduit includes a first supply conduit, and a second supply conduit. The first supply conduit connects the branch and the tank. The second supply conduit connects the branch at a first connecting position and the valve. The return conduit connects the tank and the branch at a second connecting position higher than the first connecting position in a height direction along a height of the air bleeder to return lubricant to the tank and to remove air from lubricant in the lubricant supply conduit.

An oil tank assembly for a gas turbine engine may include an oil tank having an upper compartment and a lower compartment. A baffle may separate the upper compartment of the oil tank from the lower compartment of the oil tank. A de-aerator may be included, where the de-aerator includes an oil inlet, a de-aerator outlet, and an air vent. The de-aerator may be configured to separate air from oil in an air-oil mixture such that the oil flows through the de-aerator outlet and such that the air flow through the vent. Further, the de-aerator may include a fill port for receiving oil.

A vehicle driveline component with a housing, a rotary power transmission system, a lubricant and a lubrication de-aerator. The housing defines a cavity and a sump. The rotary power transmission system is received in the cavity and includes a plurality of gears that are in meshing engagement. The lubricant is received in the sump and is employed to lubricate the rotary power transmission system. The lubrication de-aerator is received in the housing and has at least one matrix of de-aeration cells that extend between an upper surface and a lower surface. Each of the de-aeration cells has a cell inlet, which is formed through the upper surface, and a cell outlet that is formed through the lower surface. Each of the de-aeration cells tapers between its cell inlet and its cell outlet.
