Title: Hydraulic rotary positive displacement pump
IPC: F04D/
Filed: 1971-01-11
Abstract: 1312432 Rotary positive-displacement pumps ROBERT BOSCH GmbH 11 Jan 1971 [2 April 1970] 1224/71 Heading F1F In an hydraulic pump of the outwardly-sliding- vane type a ring 16 is mounted pivotally on a fixed pin 17 so that its eccentricity can be varied and in combination with a housing member 12 and end covers 10, 11 defines a chamber 13 above throttling gaps 26, 27. Inlet and outlet recesses 28, 29 are formed in an end cover member 11. As fluid flows to a discharge port 31 from the recess 29 by way of a recess 30 and the chamber 13, the pressure differential across the gaps 26, 27 urges the ring 16 away from a stop 22 against the action of a spring 23, the flow rate at the port 31 being thus rendered substantially constant irrespective of the speed of the rotor 15. A piston 34 to which pressure is transmitted from the port 31 prevents movement of the ring 16 in response to pressure changes on the high-pressure side of the rotor. Axial pressures are balanced by provision of a recess 30'. In a modification, Fig. 3, the piston 34 is replaced by a piston 40 with a separated spring-loaded extension 43, the spring 23 being dispensed with. When open a pressure-relief valve 47 inter-connects a chamber 45 and the lowpressure side of the pump. In other embodiments, Fig. 4 to 7 (not shown), the ring is movable transversely relative to the rotor axis and an adjustable throttle is provided, in the housing member, Fig. 4; the ring has diametrically opposed pins mounted in the housing so as to be movable as in the Fig. 4 embodiment and two pressureloaded pistons prevent the ring tilting, Fig. 5; the ring has diametral slots engaging with fixed axial pins or rollers so as to be movable as in the Fig. 4 embodiment, Fig. 6; and the ring has a throttle therein and engages with sealing members in place of the gaps (26), (27), Fig. 7.

[Class 120 (iii).] Coir fibre, animal hair, and the like is rubbed and rolled and propelled through a space of diminishing cross section to provide a frictional movement under increasing pressure between the individual fibres which are thereby curled and polished. Portions A of fibre are fed by rollers 10 into compartments between a drum 4 and arcuate elements 8 which are ribbed parallel with the drum axis and covered with buckskin or other suitable surfacing, the fibre being rubbed by brushes 6, the outer surfaces of which are cut spirally or tangentially to the circumference of the drum 4. Alternate partitions 3 forming the walls of the compartments have perforations 9 which arrest and turn back the elongated ends of the fibre portions which are thus continually rolled about different axes and tend to become spherical. Doors 11 are automatically opened after, for example, 10 revolutions of the drum 4 and the fibre balls about one inch in diameter delivered by centrifugal force, the balls being then teased out in an upholsterer's carding-engine. The compartments may be 3 or 4 feet in diameter, ¥ inch wide, and the drum may rotate at 200 to 300 revolutions per minute. In the case of coir fibre portions may be about one gram in weight. The drum may be fixed and the casing rotate ; the rubbing elements may be stepped or may be resiliently mounted ; the drum may be eccentric in the casing ; there may be a plurality of drums ; and the chamber may be helical, or longitudinal, the rubbing elements being carried by a flexible conveyer.
