Abstract: A high pressure monitor includes an outlet body with a transverse passage, which extends through the body to form two inlets of the outlet body, and a second passage, which is in communication with the transverse passage and extends through the outlet body to form an outlet. The monitor further includes first and second bodies, with the outlet body mounted between the first and second bodies. Each of the first and second bodies has a transverse passage, which are in fluid communication with the inlets of the outlet body. A first swivel joint is provided between the outlet body and the first body. A second swivel joint is provided between the outlet body and the second body. Further, each of the swivel joints comprises a pressure balanced hydraulic fitting with seals and bearings, wherein the seals and bearings are oriented to reduce the axial pressure on the bearings from fluid flowing through the monitor.

Abstract: An adjustable nozzle comprising a nozzle body with an inlet, an outlet, and a passageway having a smooth bore extending between the inlet and the outlet. The passageway has an inner dimension transverse to the central axis of the nozzle and a compressible wall wherein the inner dimension is adjustable to adjust the flow rate through the nozzle.
