Abstract
1481926 Stuffing boxes BALCKE-DURR AG 1 April 1975 [2 April 1974] 13229/75 Heading F2B In order to prevent sudden axial expansion of packing 3 in a piston pump, incompressible fluid in the space in which compression spring 6 is carried can, as the packing tends to expand on being relieved of fluid pressure, only escape slowly through the constricted gap 8 since, in this condition, the end gap 11 is closed by the spring. On the compression stroke, the end gap is opened by fluid pressure, so that the fluid enters the space freely via axial recesses 12, while the packing 3 is being axially compressed. The throttling effect of the gap 8 may be increased by the provision of labyrinth and like sealing formations (Figs. 3-6, not shown).
