Abstract: An irrigation sprinkler nozzle assembly including a pressure regulator having a low friction seal for a riser assembly in which the regulator is installed. The pressure regulator includes a movable portion, a fixed portion located upstream of the movable portion, and connectable to a water inlet, and a biasing member such as a spring which applies a force to the movable portion according to a pressure differential between the water inlet pressure and a reference pressure. The fixed and movable portions move relative to each other according to the force provided by the biasing member to provide a variable flow restriction which maintains the desired pressure. The low friction seal is a diaphragm connected at one end to the movable member and anchorable at another end in the nozzle head.

Abstract: A riser seal cartridge for an irrigation sprinkler. The cartridge is formed of a rigid self support shell, and a sealing member formed of a resilient material covering the shell in areas which provide the seal. The sealing member includes a first portion which seals the top end of the sprinkler body, a second portion which seals an outer surface of the riser, a third portion which connects the first and second portions, and a fourth portion extending from the third seal portion which provides a seal for the support shell lower end portion. The first seal portion provides a high pressure seal to prevent leakage when the riser is in a fully extended position; and the second seal portion provides a low pressure seal during pressure build-up as the riser is extending.
