Abstract: A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine assembly positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet. The fluid causes the turbine assembly to rotate about a center rotational axis within the housing. The turbine assembly comprises a first turbine portion and a second turbine portion that are separately formed from each other and attachable together. The first turbine portion comprises a plurality of first vanes and the second turbine portion comprises a plurality of second vanes.

Abstract: A rotating separator has a housing preventing separated liquid carryover. A plenum between the annular rotating separating filter element and the housing sidewall has one or more flow path separating guides minimizing the flow of separated liquid to the outlet. The flow path guides may include one or more fins and/or swirl flow dampers and/or a configured surface.

Abstract: A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.

Abstract: A crankcase ventilation system having a crankcase ventilation filter and a filter drain. The crankcase ventilation filter vents blow-by gases from a crankcase and separates oil from the blow-by gases. The crankcase ventilation filter drain collects oil separated by the crankcase ventilation filter and returns the separated oil to the crankcase or another component of the engine. A nozzle is coupled to a pressurized oil supply and directs an oil jet into a mixing bore of the system, which draws the oil back into recirculation. A valve is coupled to the filter drain and is configured to prevent collected oil from reentering the crankcase ventilation filter through an opening that connects the filter drain to the filter.

Abstract: Fuel filtration systems having an automatic drain assembly for water that accumulates in the filter housing are described. The filtration system includes a filter media that is configured to remove particulate matter and dispersed water contained within the fuel. The water is drained to a drain reservoir within the filter housing where the water collects. When the water reaches a threshold level, a controller initiates a warning to the engine operator, such as a dashboard light, that instructs the operator to shut the engine off. When the engine is shut off, the collected water is drained through a valve of the automatic drain assembly. In some arrangements, the automatic drain assembly can be retrofitted to existing fuel filtration systems thereby reducing the cost of fitting the automatic drain assembly to existing internal combustion engines.
