    摘要: A pump nozzle for a pump, the pump nozzle includes a plunger, a connecting rod, a compression bar, a bushing, a cylinder, and a spring. The cylinder is fixedly attached to the bushing and is equipped with a paddle. When the compression bar is pressed downward, the spring is compressed, a valve between the plunger and the compression bar opens, and the paddle stays put to seal a bottom of the cylinder. When the compression bar is released and allowed to bounce back, the valve between the plunger and the compression bar closes, causing suction by negative pressure to raise the paddle up and draw liquid , fluidic or gaseous content into the cylinder.

    摘要: A device for choking a fluid flow, with a pot-like base body, in the base of which a first passage opening is arranged, and a closing body guided axially moveably in the pot-like base body against a spring force of a spring element and having a second passage opening that forms a static choke point with a predefined fixed opening cross section. The closing body in combination with the spring element and the first passage opening forms a dynamic choke point with a dynamic opening cross section that is variably adjustable depending on a pressure difference.

    摘要: A reciprocating positive displacement pump is disclosed for pumping oenological liquids such as wines, musts, distillates, vinegars and the like, alimentary oils and other alimentary liquids and/or beverages such as fruit juices and pulpy and sugary juices. The pump is of the kind which has a reciprocating piston and distributing ball valves utilizing rubber-covered balls, and comprises a double-action hydraulic cylinder for actuating the piston, the hydraulic cylinder being fed by a central distribution unit which is in turn fed by a source of presurized fluid. The piston has a cam member mounted to its stem. The cam member is movable between contact with two limit switches upon reciprocation of the piston so as to cause direction reversal of the piston. Further, a rotating member can be provided in contact with the cam member, so as to rotate the cam member and thus, the piston stem and piston.

    摘要: A pump consists of a valve box in which a valve chamber inlet and outlet are each provided with a valve, and a reciprocating member in a cylinder that communicates with the valve chamber of the valve box to open the valves. A pressure action chamber is provided between the valve box and the cylinder and a pressure force member divides the pressure action chamber into a valve chamber side and a cylinder side. On the cylinder side of the pressure action chamber thus divided is an action medium that transmits to the pressure force member changes in the volume of the pressure action chamber produced by the action of the reciprocating member. A valve device consists of a concave valve seat and a number of fluid passages formed therein. Which open into the recess formed by the concave valve seat. Either the valve seat or the valve-piece is formed of, or covered with, a hard resilient material, or one is formed of the hard resilient material and the other is covered with a hard resilient material. The valve seat and valve-piece may also be made of wood.

    摘要: A check valve having a dual valve seat, a valve member, a retainer, and a valve spring. The dual valve seat has a cylindrical body having an axial bore therethrough. A conical valve seat is provided at one end of the axial bore and a flat valve seat is provided at the other end of the axial bore. A recess is provided in the face of the cylindrical body at the end having the conical valve seat to form a first retainer seat and an annular recess is provided about the flat valve seat to form a second retainer seat by inverting the valve seat, the check valve may accept either a stem valve member having a conical sealing surface or a flat valve member having a flat sealing surface. The embodiment of this check valve in an electromagnetic fluid pump permits it to have different operating characteristics depending on which valve member is used.
