A device for supplying injection water capable of stably supplying the water to a water injection system of a vehicle. The device for supplying injection water includes a storage unit configured to store water, a management unit mounted on the storage unit and configured to detect a state of the water stored in the storage unit and manage the water, a transport unit connected to the storage unit through the management unit and configured to outwardly move the water, and an integrated controller configured to control operations of the management unit and the storage unit.

A backflow of liquid inside a filter device during an operation of an internal combustion engine is allowed to be obviated while air inside the filter device is purged so as not to generate bubbles in the liquid. An outflow portion that includes a cylindrical portion having a substantially bottomed cylindrical shape and a back pressure valve provided inside the cylindrical portion is provided so as to penetrate a bottom surface of a case. In addition, a lid body provided on the case and an upper plate of a filter element so as to cover an upper end of the case has a first hole that communicates between a space inside the case and a space outside the case. When the back pressure valve opens (a valve body does not abut on a first valve seat), a space inside the filter element communicates with the space outside the case via a second through-hole formed in a side surface of the cylindrical portion.

The disclosure relates to a filter head comprising a housing having one inlet and at least one outlet for being connected to an on-site water pipe. A filter candle having a filter candle inlet and at least one filter candle outlet can be installed in the filter head, and the filter head has means for setting a desired degree of softening by setting a blend ratio. The filter head comprises a flow meter and at least one conductivity measuring device, in particular a conductivity measuring cell, and the filter head has an interface for data transmission to an external unit and an integrated computing unit.

A screen element for a fuel system includes a first screen and a second screen. The first screen defines a first aperture and the second screen defines a second aperture. The first aperture and the second aperture are arranged out of circumferential alignment with one another such that a torturous flow path is defined through the apertures for capturing particles smaller than the apertures in a collection cavity defined between the screens.

There is disclosed a tool for filtering a lubricant to meet a target ISO cleanliness code. The tool includes a skid-mounted integrated filtration system having a pump that circulates a flow of lubricant from an inlet port, through a heater, through a series of specifically sized filters, and past a digital particle counter. The filtration system also includes a user interface and a programmable logic controller (PLC) configured to track outputs from the pump, the oil heater, and the particle counter to monitor a cleanliness of the circulating lubricant. The filtration system also includes a filtration operations server in communication with the PLC and configured to implement a tracking and monitoring software application enabling control of the filtration system from the system itself or remotely through one or more remote user terminals such as a smartphone, a laptop or tablet computer, and the like. Other embodiments are disclosed.

The present invention relates to an inlet screen adapted to be arranged at the water inlet (8) of a hydropower plant and comprises a plurality of elongated bars (20), said bars (20) being separated by a distance holding means, each elongated bar (20) having in its elongation a proximal portion and a distal portion, and an upstream region and a downstream region, said upstream and downstream regions being at an angle in relation to said proximal and distal portions, at least one of said bars (20) defining a space (36; 36a) extending along at least a portion of the elongation of said bar (20), said bar (20) being provided with an electric heating means (31). In accordance with the invention, said elongated bar has an elongated intermediate portion (38a), said space (36; 36a) being defined in either of the upstream region (35a) and the downstream region (35b), said intermediate portion (38a) extending along the elongation of the bar (20) between the upstream region (35a) and the downstream region (35b), said electric heating means (31) comprising at least one electric heating member (37) being introduced into said space (36; 36a).

A filter assembly comprises a housing defining an internal volume. A housing second end of the housing defines at least one female thread. A bowl is positioned at the housing second end The bowl comprises at least one bowl male thread structured to engage the at least one female thread of the housing so as to be coupled thereto.

A head made of metal is provided covering an opening of a filter case, and a filtration member having a tubular shape is provided in an internal space formed by the filter case and the head. A plate made of metal is provided near the opening of the filter case, and an IC tag is provided between the filtration member and the plate. The head is provided with an antenna unit including an antenna section including an antenna configured to communicate with the IC tag. The antenna unit includes a case having a rod shape and at least partially inserted into the head, the antenna section is provided adjacent to a first end corresponding to one end of the case, the case is provided in the head such that the antenna section is exposed when the head is viewed from a side of the filter case, and the plate is provided with an aperture from which the IC tag is exposed.

A washing machine including a drainage pump to discharge water from a tub of the washing machine through a drainage passage, a first filter to which the water flows due to the drainage pump and provided along the drainage passage to filter out foreign matter equal to or greater than predetermined size, and a second filter to which the water flows from the first filter and provided along the drainage passage and to filter out foreign matter smaller than the predetermined size, wherein the drainage passage includes a first connecting hose to guide the water to flow from the tub to the first filter, a second connecting hose to guide the water to flow from the first filter to the second filter, and a drainage hose to guide the water to be discharged from the second filter to the outside of the washing machine.

A filter device that facilitates maintenance is provided. A case that internally includes a filter element includes a lid body. The lid body includes a flange portion having a substantially cylindrical shape fixed to the case and a cover having a substantially plate shape detachably provided to the flange portion. The flange portion has a first hole, and the cover has a second hole. The first hole and the second hole communicate between a space inside the case and a space outside the case.
