Abstract
Disclosed are a hydrostatic pressure support and a spherical pump having the same. The hydrostatic pressure support is arranged between each of two parallel sides of a slipper and a sliding groove, and includes a first liquid flow channel, a second liquid flow channel, and a pressure-bearing groove. An inlet of the first liquid flow channel is communicated with one of two working chambers of the spherical pump, and an inlet of the second liquid flow channel is communicated with the other of the two working chambers. An outlet of the first liquid flow channel and an outlet the second liquid flow channel are respectively communicated with the pressure-bearing grooves provided on the two parallel sides of the slipper.
