Abstract: A nozzle assembly includes a nozzle body, a first flow straightener coupled to the nozzle body, and a second flow straightener coupled to the nozzle body. The nozzle body defines an inlet, an outlet, and a nozzle body passage extending between the inlet and the outlet. The first flow straightener extends at least partially across the nozzle body passage and defines a first passage and a second passage each fluidly coupling the inlet and the outlet. The second flow straightener extends at least partially across the nozzle body passage and defines a third passage and a fourth passage each fluidly coupling the inlet and the outlet.

Abstract: A nozzle assembly includes a nozzle body and a flow straightener. The nozzle body defines an inlet configured to be fluidly coupled to fluid source, an outlet, and a nozzle body passage extending between the inlet and the outlet. The flow straightener is coupled to the nozzle body and extends at least partially across the nozzle body passage. The flow straightener defines a primary passage and a secondary passage extending through the flow straightener to fluidly couple the inlet and the outlet of the nozzle body. The primary passage defines a primary passage outlet having a cross-sectional area, and the secondary passage defines a secondary passage outlet having a cross-sectional area that is less than the cross-sectional area of the at least one primary passage. At least one of the primary passage outlet and the secondary passage outlet has a circular cross-section.

Abstract: A constant pulling force winch control system includes a sensor that senses a degree of winding of a winch cable around a winch drum, and a control system configured to control a winch motor to achieve a constant pulling force on the winch cable based on the degree of winding sensed by the sensor. The sensor may be a position sensor that measures a position of the winch cable relative to a centerline of the winch drum as the degree of winding. The position sensor may sense an angular position of a tension plate relative to a tensioner shaft to measure the degree of winding. The winch motor may be a hydraulic winch motor or an electric motor, and the control system is configured to control the power applied to the hydraulic winch motor to achieve the constant pulling force based on the degree of winding sensed by the sensor.
