| 摘要 |
The invention relates to a hydraulic ram pump, comprising: a propulsion water line fed with propulsion water, a delivery line which can be connected to delivery water via a bottom valve, a ram pump valve which is connected to the propulsion water line and delivery line, the propulsion water flowing into the delivery line when the ram pump valve is open and, after the closing of the ram pump valve, the water column flowing further in the delivery line sucking in delivery water via the bottom valve, the ram pump valve being held by spring force in its closed position separating the propulsion water line from the delivery line, and a pressure reservoir being provided, which is connected to the propulsion water line upstream of the ram pump valve in the direction of flow, the valve member being of annular design, axially movable and tightly connected to the delivery line, the effective cross section of this connection being larger than the cross section of the valve seat, and the valve seat of the ram pump valve and the valve seat of the bottom valve being mechanically coupled in order to transmit kinetic energy.
