摘要: A vane pump delivers pasty materials, particularly sausage stuffing, for the purpose of filling doses of the stuffing into sausage cases. The flow of material into the pump chamber generally takes place by a stuffing device in the hopper and by the action of the vacuum to which the vane pump is exposed. The degree of filling and therefore the dosing accuracy is improved by providing a curved portion in the transition area between the inner wall of the cylindrical part of the cup-shaped pump casing and the base part of the latter receiving the pump rotor mounting.

摘要: A unitary pump, regulator valve/pulsation dampener, and interconnecting passageways is provided. The regulator valve/pulsation dampener includes a flexible member disposed in a chamber arranged between the fluid input and fluid output. The diaphragm flexes as a function of the pressure in the chamber to control the opening and closing of a bypass valve member and, in addition, damps out both high and low frequency pulsations generated in the ink by the pump. When the pressure in the system increases beyond a predetermined limit the valve member is opened to divert some of the fluid flow into a bypass passageway until the pressure falls below the predetermined limit. The pressure limit in the system can be varied by adjusting the external pressure applied to the flexible member using an adjustment screw and compression spring.

摘要: An axial variable capacity rotary pump which yields a stepless change of capacity. The pump has a casing with an inlet and outlet, at least one rotary member with engaging elements mounted on the periphery of the rotary member for engaging a mating member, and a pair of axial sealing element which seal either axial side of the rotary member. One sealing element moves together with the rotary member axially to change a length of a sealed working chamber between the members, thereby changing the delivery capacity per revolution of the pump.
