The present invention relates to a metering system for metering a fluid metered medium, with a suction line that is filled with a metered medium at fluid pressure ps, and a pressure line that is filled with the metered medium at fluid pressure pd, wherein the suction line is connected to the pressure line via a metering member constructed as a metering pump, with which metered medium can be conveyed from the suction line into the pressure line, wherein the metering pump has a delivery chamber, the volume of which can be varied with the assistance of a movable displacement element in such a manner that the delivery chamber has a minimum volume Vmin in a first position of the displacement element and a maximum volume Vmax in a second position of the displacement element, wherein the delivery chamber is connected via a pressure valve to the pressure line and via a suction valve to the suction line, such that, by means of an oscillating movement of the displacement element, metered medium can alternately be drawn out of the suction line via the suction valve into the delivery chamber and metered medium can be discharged from the delivery chamber via the pressure valve into the pressure line. In order to provide a metering system and a metering pump adapted thereto which has a high efficiency, no leakage flow and is easy to construct, according to the invention the formula (I) is provided where κ = 1.5.

The present invention relates to a displacement pump comprising a delivery chamber, which is connected to a pressure connection and a suction connection, a displacement element determining the volume of the delivery chamber, said element being able to be moved backwards and forwards between a first position in which the delivery chamber has a smaller volume and a second position in which the delivery chamber has a greater volume, wherein the pressure connection is connected to the delivery chamber via a pressure valve and the suction connection is connected to the delivery chamber via a suction valve. According to the invention, in order to provide a displacement pump that can be manufactured simply and inexpensively and simultaneously reliably provides a degassing function, which enables downtimes to be reduced and the reliability of the delivery process to be enhanced, a backflow channel connects the delivery chamber and pressure connection when the pressure valve is closed, via which pressure connection the medium can enter the delivery chamber and/or gas can escape from the delivery chamber.
A pressure retention valve including a housing having an inlet passage and an outlet passage that can be connected together and a separating diaphragm subdividing the housing into two portions, wherein, in operation of the valve, a first portion conveys fluid and a second portion is fluid-free. The valve further includes a valve seat defining an end of the inlet passage, arranged in the fluid-conveying portion of the housing, and has a first sealing surface, a shut-off body which is arranged movably in the fluid-conveying portion of the housing and has a second sealing surface, and a spring element having a spring force, which is arranged in the fluid-free portion of the pressure retention valve. The spring element is so arranged that its spring force prestresses the second sealing surface in the direction towards the first sealing surface so that in a position of the shut-off body that closes the valve the sealing surfaces are in engagement with each other and the shut-off body separates the inlet passage from the outlet passage. The inlet passage is so arranged that a fluid flowing in through the inlet passage in operation of the valve is applied to the shut-off body in such a way that the fluid exerts on the shut-off body a force which acts in opposition to the spring force of the spring element. The shut-off body has a guide portion which extends into the inlet passage, and the inlet passage is portion-wise of such a design configuration that it forms a guide bush in which the guide portion of the shut-off body is guidedly received.

MEMBRANE PUMP HAVING AN INERTIALLY CONTROLLED LEAKAGE COMPENSATION VALVE
The present invention concerns a membrane pump having a hydraulic chamber (8) separated from a pumping chamber (9) by a membrane (1), wherein the pumping chamber (9) is respectively connected with a suction connection and a pressure connection and a pulsating working fluid pressure can be applied to the hydraulic chamber (8) which can be filled with a working fluid, wherein the hydraulic chamber (8) is connected to a working fluid reservoir (15) via a leakage compensation valve (6), wherein the leakage compensation valve (6) comprises a closing body which is held in a closed position with the aid of a pressure element and which can be moved to and fro between the closed position in which the valve gate is closed and an open position in which the valve gate is open, wherein the pressure element is designed such that when the pressure in the hydraulic chamber (8) is lower than a set pressure p L, the closing body (16) moves in the direction of the open position. In order to provide a membrane pump with a leakage compensation valve which reduces or even overcomes the disadvantages of the prior art, the invention proposes that the mass of the closing body (16) is large enough for the closing body (16) to move by no more than 0.2 mm in the direction of the open position when a drop in pressure to 0 bar which lasts no longer than 1 millisecond occurs as a result of a pressure pulse in the hydraulic chamber (8).

A magnetic drive metering pump in which a movable thrust member is fixed to a diaphragm and is axially movable in a magnet shroud. The thrust member, on electrically actuating the magnet shroud, is drawn into the magnet shroud against the force of a recuperating spring, and after deactivating the magnet shroud, is returned to a starting position. The diaphragm cooperates alternately with an outlet and an inlet valve to produce a pump stroke in a pump metering head. The magnetic drive metering pump has a reference element associated with the thrust member and diaphragm, the position of which reference element is detected by a positional sensor. The positional sensor provides a signal which has a fixed relationship to the position of the reference element, and the motion of the thrust member is controlled by a control circuit such that it follows a predetermined nominal profile.
