Abstract

The pump drive system is for pumps handling liquids or gases or producing a vacuum, and produces reciprocating movement of the piston element without the need for a crank housing. This is achieved by driving the sliding hollow piston element by means of a rotating eccentric disc inside this element. The disc has internal gear teeth engaged by planetary gear wheels driven by the pump shaft. Valving is provided by spring biassed ball valves in the inlet and outlet ports. The eccentric movement of the drive is converted to reciprocate by use of idler planetary gears.

Description

Petr.:Antrag auf Patebnterteilung für eine universellePetr .: Application for granting a patent for a universal

"Hydraulik- und Phenumatikpumpe" Anwendungsgebiet : Diese Erfindung ist ein Element, welches Anwendung findet in fast allen Hereichen der Hydraulik und Pneumatik, als Druck-, Saug-oder Vakuumpumpe: Stand der Technik: Bisher Vorhandenes sind herkömaliche Pumpen, wie Kolben, Zanhard, Flügelpumpen usw.. "Hydraulic and Phenumatic Pump" Field of application: This invention is an element that is used in almost all hydraulic systems and pneumatics, as pressure, suction or vacuum pumps: State of the art: Previously available are conventional pumps, such as piston, Zanhard, vane pumps, etc.

Kritik der Technik: Verbesserung der herkömmlichen Pumpen durch gewaltige Verkleinerung das Umfangs der Pumpanlage bei größerer Förderleistung.Criticism of the technology: Improvement of the conventional pumps with huge ones Reduction of the size of the pumping system with a larger delivery rate.

Aufgabe: Die Aufgabe der universellen "Hydraulik- und Pneumatikpumpe ist, - enormen Raum einzusparen (ohne Kurbelgehäuse) -größere Förderleistung (jeder Hub-Arbeitsschub) -Energieensparung - variable Ar-wendung als Hydraulik-, Pneumatik-, Saug-, Druck-, oder Vakuumumpe Lösung: Diese Verbesserungen werden erreicht,durch die Möglichkeit der Extrenterscheibe mit Innenverzahnung aus einer "Drehbewegung" eine "Hubbewegung" ohne Kurbelwelle zu erzeugen.Task: The task of the universal "hydraulic and pneumatic pump is - to save enormous space (without crankcase) - to increase the delivery rate (every Lift-work thrust) -Energy saving - variable application as hydraulic, pneumatic, Suction, pressure, or vacuum pump solution: These improvements will be achieved, thanks to the option of using the extra wheel with internal teeth from one "Rotary movement" to generate a "lifting movement" without a crankshaft.

Erzielbare Vorteile: Seine unter Aufgabe Beschreibung: Bei Antrieb der Achse wird ein Planetenrad im Inreren des @a@ kranzes angetrieben,welches die Kraft auf den Zahnkranz übertragt und somit die Extrenterscheibe in Drehung und gleichzeichtig in eine Hubbewegung versetzt, innerhalb des Rolbengehäuses. Durch 2 Dichtungsdeckel (mit eingestzten Kugellagern für Antriebsachse) wird der Hubraum abgedichtet.Bei jeder Hubbewegung wird in den Eubraum durch das jeweilige Einlaßventil gepreßt; Masse angesaugt und bei Gegenhub aus dem Auslaßventil gepreßt! (Funktion durch beiliegende Schema-Zeichnnungen ersichtlich.) PatentansprUche: System des Bewegungsablaufes der Kolbengehäuse beweglichen Teile.Achievable benefits: Its under task Description: When driving the axis is driven by a planet gear in the interior of the @ a @ ring, which the Force is transmitted to the ring gear and thus the extreme disk in rotation and at the same time set in a lifting movement within the roller housing. By 2 sealing covers (with inserted ball bearings for the drive axle) are the cubic capacity With each stroke movement, there is a flow into the Eubraum through the respective inlet valve pressed; Mass sucked in and pressed out of the exhaust valve on counter-stroke! (Function evident from the attached schematic drawings.) Patent claims: System des Sequence of movement of the piston housing moving parts.
