ABSTRACT:
High pressure fluid apparatus having a swivel flow divider connected to a rotary power source and an accompanying power cylinder for transferring high pressure fluid from a stationary to a rotary medium and a fluid jet rotary bit. The swivel flow divider defines a pair of integral seal bearings which can be variably positioned by means of the power cylinder to divert substantially all of the fluid flow into a fluid conducting tube at high pressures, e.g. up to about 10,000 psi to about 20,000 psi to divert fluid flow to a relatively low pressure region surrounding the fluid conducting tube, or to apportion fluid flow between the tube and the low pressure region surrounding the tube. The fluid jet bit has a bit body including a wear resistant insert which can be removed from a fluid jet housing and mounting without subjecting fluid jet orifices secured in the latter to damage.
