    Abstract: A removable and replaceable end cap that selectively lockingly engages a seat ring of a filter housing. The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element. The filter element, which may be coupled to the end cap, may be adapted to remove particulate or contaminate from the received fluid.

  • Patent number: 10049841
    Abstract: Applicant has created systems, methods, and apparatuses for controlling the power supply of a vacuum cleaner motor. The systems and apparatuses include pressure taps to detect a pressure differential within a vacuum cleaner, a float that adjusts depending on an amount of liquid stored, and a power switch that toggles based on the pressure differential created by the position of the float. Alternatively, the float can be replaced by an air chamber so that the pressure differential is created by liquid rising above the volume of air trapped in the chamber. The method can include interrupting the current supplied to an electrical circuit of a power switch based upon a pressure differential created within the vacuum. By controlling the power supply to a vacuum cleaner motor based on a pressure differential created by the amount of liquid stored within the vacuum cleaner, the vacuum cleaner can automatically disable the vacuum cleaner's motor as the vacuum approaches its maximum liquid capacity.

  • Patent number: 8540789
    Abstract: A filter element comprises a pleated filter (10), one end of which is received in an end cap (11), which is made up of a unitary molding comprising an end part (21) of a harder plastics material, and a lower part (22) of a softer plastics material, the plastics being compatible or of the same composition, differing only in hardness. A groove (24) engages with a support plate (14), the groove being formed in the softer material abutting the harder material so that the latter forms one face of the groove. A perforated support sleeve (29) can be inserted by dropping into the filter, and an end cap (12) at the other end of the filter either closes the end or is adapted for connection to a further similar filter.

  • Patent number: 8413293
    Abstract: A vacuum cleaner includes a dust collection chamber, a cover configured to close the dust collection chamber and a mount for a dust bag disposed in the dust collection chamber. The mount is pivotable about a pivot axis from a first position blocking a closure path of the cover to a second position in which the mount does not block closure path of the cover. The mount is pivotable into the second position upon receiving of the dust bag. The location of the mount in the first and second positions and a position of the center of gravity of the mount relative to the pivot axis are configured so as to automatically pivot the mount from the second position to the first position when the dust bag is removed from the mount and when the vacuum cleaner is disposed in a normal operating position on a substantially level surface.
