An intermittently assisted hydrostatic bearing (10) for a hydraulic apparatus having a rotatable surface which is periodically assisted from a pressure balance of less than 100% to a pressure balance greater than 100% pressure balance includes a pressurized fluid supply source (28) for supplying a pressurized fluid, a supply channel (30, 31, 32 and 34) for supplying pressurized fluid from the pressurized fluid supply source to a point (36) between cooperating opposed bearing surfaces (24) and a pressure producing device (48) which communicates with the fluid supply channel and in response to a command signal causes the hydrostatic bearing to attain a greater than 100% pressure balance. The invention further includes a check valve (60) positioned in the supply channel (32) to prevent the reverse flow of fluid into the pressurized fluid supply source (28).
