摘要： An extrusion method and an extruder, the material to be extruded being fed with a material feeding device (1) into a radial pump unit included in the equipment. The radial pump unit comprises conical gearwheels (2) which are adjacently positioned and rotate in opposite directions. The radial pump unit transfers the material in an annular flow into the extruder's nozzle (4). Additional material (20) can be supplied into the product through the radial pump unit.

摘要： The invention relates to a high pressure cleaning device comprising a motor driving an internally toothed gearwheel pump for supply of a cleaning fluid, under high pressure, to an outlet device. Said internal tooth gear and/or an external tooth gear comprise a molybdenum containing chrome steel alloy which also contains a nitrogen component of 0.1 - 1 % and which increases the corrosion resistance and hardness of the toothed gearwheels.

摘要： A screw pump (2) for feeding highly viscous material such as mixed concrete and the like. Plural projections (4a) engage the helical screw of the screw pumps to facilitating removal of the material such as gravel caught in the screw pump. Further for preventing excessive force from being exerted on the screw because of material caught in the screw pump, a spring is interposed between partitioning plates (5) and hydraulic cylinders (cy) or crank mechanisms. Further, to make the position of the holder (16) for the partitioning plate (5) stable, plural rollers are provided above the holders.

摘要： A volume-expansion rotor machine comprises a casing (1) in the spherical cavity of which is mounted a rotor. The rotor has a spherical form and consists of a disk-shaped partition (2) hingedly connected, on its opposite sides, with blades (3, 4). The blades (3, 4) are connected with the partition (2) along its diameter, are mutually perpendicular and are connected with power take-off shafts (5, 5') oriented at an angle to each other. The hinged connection of the partition (2) to each blade (3, 4) consists of a cylindrical protrusion (9, 9') provided on the partition (2), engaging with a reciprocal groove (10, 10') on the end-face part of the blade (3, 4). Axes (a, b) of the protrusions (9, 9') of the partition (2) are mutually perpendicular and are located in one and the same plane.

摘要： The present invention relates to a screw pump of the type comprising a screw (1) rotatably arranged in a housing the threads of which screw are partially in engagement with a rotatable sealing device (11) comprising radial sealing discs (16), whereby the screw area of the screw, including thread grooves and thread walls, are formed by a generatrix which is a part of a circle arc, the circle of which is rotatable around an eccentric rotation axis when the generatrix rotates around the axis of the screw and is displaced along this with a velocity being proportional to the rotational velocity of the screw and wherein the sealing device comprises at least one circular disc the eccentric rotational axis of which, which is arranged transverse to the axis of the screw coincides with the rotation axis of the generatrix, i.e., the rotation axis of the disc is a tangent to the generatrix, whereby the screw (1) is mounted in one end (2), and that the screw has a radially, partially extending broad flange (24) without any rise in a cross section immediately above the sealing device (11).

摘要： A spherical gear pump comprises a housing with a first longitudinal axis (58), a spherical seat (19, 41) an inlet (21) and outlet (23) adjacent the seat, inlet and outlet passages (25,31) communicating with the inlet and outlet and adapted for connection to a source of liquid and a liquid load. A hemispherical gear (53) is rotatively mounted within the seat and includes a plurality of peripherically spaced radial gear teeth (79) and a drive shaft (55) for rotation about the first axis (58). A hemispherical cam (101) is adjustably positioned within the spherical seat having an arc less than 180°, and radial cam surfaces (103) facing the spherical gear (53). A plurality of separate symmetrical radial gear teeth (81) are pivotally mounted within and between the teeth (79) of the spherical gear (53) with each separate gear tooth having a radial top wall (87) centrifugally biased against the cam surfaces on rotation of the spherical gear and a bottom wall (85) adapted for pivotal movements within planes passing through the first axis on rotation of the separate gear teeth over the cam surfaces.
