20 onstruction unctional principle he rotational movement of the motor () is converted via the worm gearing (2) and eccentric (3) into the reciprocating movement of the piston (6) creating the suction and discharge stroke. he piston has a hollow bore and a series of radial hydraulic control holes, which provide the hydraulic connection between the drive and the piston stroke. he control sleeve (5) covers the holes during the stroke and seals the stroke area from the drive area. he hydraulic P diaphragm (0) displaces a metered volume of dosing liquid from the dosing head () into the dosing piping. On the suction stroke, the piston creates a low pressure in the dosing head; the ball valve (3) on the discharge side is sealed by the line pressure and the dosing liquid flows through the suction valve (2) into the dosing head. he stroke volume size is solely determined by the position of the control slide. he active stroke length and corresponding average dosing flow can be changed continuously and linearly from 0 to 00 % using the stroke-length adjustment knob and micrometer scale (). he safety valve (7) acts as both a pressure relief valve and a hydraulic oil degassing valve. It opens if the pressure in the dosing system is over the set pressure and by-passes hydraulic fluid, thus protecting the pump from overpressure. he degassing valve ensures a constant, high dosing accuracy by removing air from the hydraulic oil. he unique diaphragm protection system AMS (9) touches and rides on the dosing diaphragm (0). If the suction or discharge line is blocked due to a fault in the system, the AMS valve seals the hydraulic chamber. Although the piston (6) continues moving, the diaphragm cannot be overstretched. 20

43 7 Multi-function valves, pressure relief valves, pressure loading valves Multi-function valves combine the functions of pressure relief valves and pressure loading valves. In addition, they allow deaeration of the pump and emptying of the discharge line for maintenance. Pressure relief valves, or safety valves, protect the pump and the discharge installations against excessive pressure. All pressurized dosing installations should include a pressure relief valve. Pressure loading valves maintain a certain backpressure for the pump. hey are used in applications with too low backpressure or no backpressure at all. Pressure loading valves are also used to prevent siphoning, when the admission pressure is higher than the backpressure. hey provide a constant backpressure for the dosing pump when the system pressure is fluctuating. ig.
