초록 ▼

In a diaphragm pump the diaphragm separating the delivery chamber from the working chamber is clamped between a cylinder body and a cylinder cover in pressure-balancing arrangement. For this purpose a pressure-balancing space is provided to be radially outside and to encircle said diaphragm clamping surface, the pressure balancing space communicating with the working chamber through at least one communicating passage. Furthermore, a separate annular seal member is disposed to be radially outside the pressure balancing space chamber between the cylinder cover and the cylinder body to seal-off the pressure balancing space and the working chamber from the outside. This enables the diaphragm pump to be used at discharge pressures far greater than 350 bars and simultaneously permits the use of plastic diaphragms which are reliable in operation and have a large displacement capacity.

대표청구항 ▼

A diaphragm pump including at least one diaphragm separating a delivery chamber from a working chamber filled with a hydraulic medium, said diaphragm being firmly clamped between a cylinder body and a cylinder cover at a clamping surface formed by the peripheral edge portion of said diaphragm, and further including hydraulic diaphragm drive means in the form of a reciprocating displacement piston slidably disposed within said cylinder body between said working chamber and a hydraulic fluid reservoir, characterized in that a pressure balancing space is provided to be radially outside and to encircle said diaphragm clamping surface, said pressure balancing space communicating with said working chamber or with said hydraulic fluid reservoir through at least one communicating passage, and in that a separate annular seal member is disposed to be radially outside said pressure balancing space between said cylinder cover and said cylinder body to seal-off said pressure balancing space and said working chamber from the outside.
