Abstract: Embodiments relate generally to a cross flow blower (100) including a housing (108) which includes an inlet (104) and an outlet (102), rotating impeller blades (212) located within the housing (108), wherein airflow enters and exits the impeller blades (212) radially, a motor (106) operable to power the rotating impeller blades (212), and a plurality of flow forming blades (210, 214) located within the blower (100) operable to direct airflow within the blower (100).

Abstract: The present invention relates to a delivery pump, in particular for delivering diesel fuel into a high-pressure accumulator. The pump has a housing and a drive shaft which is accommodated in the latter and is mounted by at least one sliding bearing arrangement such that it can rotate about a drive shaft axis. The sliding bearing arrangement is formed by a bearing bore and a bearing shaft section which extends through the latter. The sliding bearing arrangement has a bearing play which extends in the radial direction between the bearing shaft section and the bearing bore and has a smaller value in the bearing center than at least one bearing edge. A delivery pump for delivering diesel fuel is therefore provided which has a low-wear sliding bearing arrangement.

Abstract: The invention relates to a piston pump for delivering hydraulic fluid, including a cylinder element, a piston that is able to move back and forth in the cylinder element, a piston chamber in which the piston is able to exert pressure on the hydraulic fluid, an outlet valve, and a slot-controlled inlet valve; the inlet valve has at least one slot that is oriented in the movement direction (X-X) of the piston.

Abstract: A liquid ring pump, includes a stationary housing having an interior space for accommodating at least one rotor mounted on a rotor shaft for rotation in the housing. The rotor shaft is supported by a bearing in the interior space, and the rotor is operated by a drive which acts on the outer perimeter of the rotor.

Abstract: A tandem-type pump assembly having a first housing and a second housing. A first main pump and a second main pump are coaxially aligned and disposed in the first housing. A first driving shaft having a first end and a second end is rotatably supported in the first housing and coaxially interconnects the first main pump and the second main pump. A driving gear is fixed to the first end of the first driving shaft for rotation therewith. A second driving shaft is rotatably supported in the second housing for driving an auxiliary pump. A driven gear is fixed to the second driving shaft for rotation therewith and directly engages the driving gear.

Abstract: A centrifugal oxygenator pump includes a bottom inlet into an impeller chamber, the bottom inlet having a venturi gas inlet for mixing gas with the in flowing liquid. The impeller chamber is of a frusto-conical shape within which is rotatably mounted a similarly shaped mismatched impeller, the impeller driving the liquid and gas mixture toward a toroidal outlet chamber and through an outlet to an outlet nozzle. The motor drives the impeller to attain a high specific speed so that an increased capacity and larger size oxygenator is provided with maximum efficiency and effectiveness.

Abstract: An assembly for sealing an interface between a high pressure steam chest or chamber and a casing, wherein high pressure steam flows from the steam chest into the interior of the casing. The assembly comprises a sealing element extending through the interface for preventing direct contact between the high pressure steam and the interface, and joined to the steam chest so that a steam tight joint is developed therebetween.
