A strainer for filtration in an oil circuit of a turbine engine, in particular a multi-flow turbojet engine, is housed in a bore of a lubrication assembly. The oil serves to lubricate and cool mechanisms of the turbine engine. The strainer includes a filtering portion as an angular tube portion and a holding structure for the filtering portion. The structure forms a thickening and exhibits rings and structural posts. A magnet is added in a socket formed by the structure. The structure and the filtering portion are integral and are produced by additive manufacturing, which simplifies production. The application likewise relates to a method of producing the strainer.

Intake arrangement for an internal combustion engine for the intake of a liquid medium from a container, having a strainer, via which liquid medium can be taken in from the container, and at least one suction pipe which opens with a first end into the strainer and via which the liquid medium can be delivered towards a suction pump, which interacts with the respective suction pipe. The suction pipe is mounted at a second end that faces away from the strainer such that it can be pivoted about an axis such that the suction pipe follows a movement of the liquid within the container.

A housing assembly, portable filter system using the housing assembly and methods of mounting a filter element in a housing assembly are provided. The housing assembly is usable with filter elements of different types. The housing assembly includes a housing body having an open end and being attached to a filter head. The filter head includes a first housing sealing interface configured to sealingly mate with a filter element of the first type and a second housing sealing interface configured to sealingly mate with a filter element of the second type. A cover member removably attaches to the housing body and includes a third housing sealing interface configured to sealingly mate the filter element of the second.

The present invention provides a strainer for use with a water pump in a mine that includes a grill for preventing the ingress of solid material over predetermined dimensions, and an air discharge structure positioned so as to produce a continuous flow of air to remove the material from at least part of the grill, so that flow is maintained through the strainer.

The present invention relates to a water purification system for a smart building that allows users to monitor a water pipe and a water quality condition and take disaster prevention response. The water purification system includes a water pipe scaler connected to the water pipe of the building and to scale an internal condition of the water pipe, a water pipe filtration device to filter a water supplied to the water pipe, a first sensor to measure a quality of the water flowing in the water pipe, a second sensor installed at the building or a ground of the building to measure a condition of the building or the ground, and a water supply control device to monitor the water quality and the condition of the building or the ground based on sensing data of the first sensor and the second sensor.

A drainage system with filter connection includes a water pump body, a water inlet pipe connected to the water pump body, a water outlet pipe connectable to the water inlet pipe in an orientation forming an annular cavity between an inner surface of the water outlet pipe and an outer surface of the water inlet pipe, a water storage apparatus in communication with the water outlet pipe, a connection fastener for connecting the water inlet pipe and the water outlet pipe to form the annular cavity, and a filter disposed at least partially within the annular cavity. A locating ring is on the periphery of the filter, a cross-section width (W) of the locating ring being greater than a spacing (L) between a front end surface of the connection fastener and a stop surface on the water storage apparatus.

A toilet device for a rail vehicle includes flushing water-carrying installations and wastewater-carrying installations. The flushing water-carrying installations include an intermediate reservoir for storing flushing water and a supply line for supplying the intermediate reservoir with flushing water. The supply line includes a filter for filtering the flushing water supplied to the intermediate reservoir. The supply line is connected to the intermediate reservoir such that flushing water from the intermediate reservoir can be returned through the filter. A backflushing line is connected to the filter and opens into a wastewater-carrying installation. A method for operating the toilet device includes supplying the flushing water through a filter to fill the intermediate reservoir, and flushing a flushable bowl with flushing water from the intermediate reservoir or backflushing the filter with flushing water from the intermediate reservoir and draining off the flushing water to a wastewater-carrying installation.

A pipeline strainer having a body with a straining element therein. The body has a Y-shape and defines a cavity to receive the straining element. The cavity may be defined in part by a recess that comprises a surface which may be used to guide the straining element as it is inserted into the cavity. The recess may form a dome. The recess, when viewed cross sectionally, may have a linear segment and a curvilinear segment. A rounded protrusion may be created on an outer surface of the body as a result of the recess.

A pipeline strainer having a body with a straining element therein. A portion of the straining element is in the path of fluid flowing from the inlet to the outlet of the body. A first end of the straining element may be parallel to the inlet, or may be coextensive with the inlet. The second end of the straining element may be disposed proximate a debris drain. A first axis from the inlet for fluid to the outlet for fluid and a second axis from the inlet for fluid to the debris drain may form an angle of less than 30. A rotatable plug may be disposed in the debris drain. The straining element may include at least one corrugation. A cover plate may be removable secured to the bottom of the body of the pipeline strainer.
