  • Patent number: 10441902
    Abstract: A strainer is provided in an interior of an injection pipe serving as an injection opening through which a liquid containing a reducing agent is injected into a tank body. In the strainer, a front end portion, having a substantially triangular or substantially trapezoidal shape when a cross section is taken along a plane including an axis of a strainer body having a substantially cylindrical shape, is formed integrally with a front end of the strainer body.
    Type: Grant

  • Patent number: 10058801
    Abstract: An adhesive applied to an inner side of a bottom surface of a plate having a substantially hollow cylindrical shape with a closed bottom fixes one end of the filter material and the plate to each other. A plurality of projections located at different positions in a circumferential direction are formed on the plate, and a leading end of each of the projections comes into contact with the filter material.

  • Patent number: 9987570
    Abstract: In a filter element, plates are provided in a manner of covering ends of an outer cylinder and an inner cylinder. A packing having a substantially hollow annular plate shape is provided on the plate. A filtering material is provided between the outer cylinder and the inner cylinder. The packing is abutted against a surface of the case in parallel with the plate and a cylindrical outflow portion having a surface parallel to the inner cylinder.

  • Publication number: 20100252494
    Abstract: A fluid supply device may include a pump device that moves fluid, and a filter device that filters fluid which flows due to operation of the pump device. The pump device may include a pump device housing that comprises a first coupling member which enables the fluid to flow therethrough. The filter device may include a filter device housing that holds a filter element. The filter device housing may have a second coupling member that enables fluid to flow therethrough. The filter device and the pump device may be coupled by a tube member that enables the fluid to flow internally between the pump device and the filter device. Preferably, at least a part of the pump device is interposed between the filter device and the wall such that the pump device overlaps with the filter device in a direction in which the base extends.

  • Patent number: 4414470
    Abstract: In a focusing position detection apparatus for detecting a focusing position by causing rays of light coming from a peripheral portion of an exit pupil of a photographing lens to enter a pair of self-scanning type photoelectric element arrays through a lenticular lens group and then detecting the difference of the phases of the output signals from the photoelectric element arrays, in order to cause the rays of light to enter accurately the pair of self-scanning type photoelectric element arrays, a pitch Po between photoelectric elements which constitute the pair of photoelectric element arrays is suitably changed relative to a pitch P between small lens element which constitute the lenticular lens group, and furthermore, in order to detect the focusing position accurately, the boundary areas in the convex surfaces of the small lens elements of the lenticular lens group are made opaque so that noises in the output signals of the photoelectric element arrays are reduced.
