<p>A pump has a housing with inlet and outlet ports. The pump element is moved by a drive spindle (5), connected to a spherical segment of carrier (6). The spindle forms an angle with the centre line of symmetry of the segment. Parts of the pump space on both sides of the intermediate disc (12) are each connected by a port in the pump casing, to the atmosphere. To improve the sealing between pump housing halves, the intermediate disc has a flange at right angles to the disc surface.</p> |
