An automotive oil-filter assembly includes a main body made from aluminum by high-pressure die casting, where a filter element mounting base and a radiator mounting position are arranged on the main body; a filter element is inserted into the filter element mounting base, and a radiator is mounted at the radiator mounting position; a main body cap is mounted on the filter element mounting base; a bypass valve is arranged at an end, adjacent to the main body cap, of the filter element and communicates with the filter element; an oil inlet of the main body is located at one end of the main body and communicates with the filter element mounting base; and an oil inlet of the radiator, an oil outlet of the radiator, a coolant inlet of the radiator, and a coolant outlet of the radiator are located at the radiator mounting position.

A filter apparatus includes a filter, such as a cartridge, positioned within a housing. The filter apparatus has multiple ports and valves, so as to allow a user to easily switch between a filtration mode of filtering fluids and a maintenance mode of cleaning the filter. The filter can have a filter substrate in a housing and after filtrate builds up on the substrate, the substrate can be cleaned by directing a spray of fluid, such as from a ring of nozzles at the top of the housing, onto the substrate. A maintenance port can be provided to drain the debris washed from the substrate. The filter can switch between a backwash mode and a filtration mode.

An oil filter for a motor vehicle includes a filter cartridge disposed in an oil filter housing. A piston of the filter cartridge is displaceable in the oil filter housing in an axial direction of the filter cartridge. The filter cartridge has a closure element where the closure element is held at an end of at least one strut of the filter cartridge and where a free end of the at least one strut is supported in the oil filter housing. The piston is displaceable relative to the at least one strut in the axial direction of the filter cartridge.

A removable filter cartridge includes a filter housing containing a filter, a sealing valve coupled to an open end of the filter housing and configured to removably couple the removable filter cartridge to a filter head. The sealing valve has an open position and a closed position that seals the filter housing, and is configured to maintain a seal of the filter housing while uncoupled from the filter head. A sealing valve includes a first end to be removably coupled to a filter head and a second end to be coupled to a filter housing to form a removable filter cartridge. A method of retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the filter housing to form a removable filter cartridge, and removably coupling the removable filter cartridge to the filter head.

This application discloses a filtering system, an air conditioning system that includes the filtering system, and a cleaning method for a filtering system. An example filtering system includes a total liquid inlet, a total liquid outlet, a first Y-shaped strainer, and a second Y-shaped strainer. The first Y-shaped strainer includes a first liquid flow port, a second liquid flow port, and a first drainage port. The first liquid flow port is connected to the total liquid inlet by using a first pipeline, the second liquid flow port is connected to the total liquid outlet by using a second pipeline, and the first drainage port is connected to a first waste liquid area by using a third pipeline. The second Y-shaped strainer includes a third liquid flow port, a fourth liquid flow port, and a second drainage port, the third liquid flow port is connected to the total liquid inlet by using a fourth pipeline.

A swimming pool backwash filtration device for filtering backwash includes a house. The house has an interior defining a space for a filter to be stored within. The house has an inlet surface and an outlet surface where the inlet surface has an inlet conduit. A y-valve comprises an intake conduit and a pair of exit conduits. The intake conduit is in fluid communication with a pump and a debris filter of a swimming pool. The pair of exit conduits includes a backwash exit conduit and a pool exit conduit. The pool exit conduit is in fluid communication with the inlet conduit of the house.

A separator for separating objects from a liquid flow in a pipe system is disclosed. The separator has a separator housing (4) and at least one filter in the form of a plurality of filter structures (29, 32) extending into the separator housing. The separator may be used in e.g. a vacuum sewage system, a water supply system, 5 or a pipe system for wastewater.
