An electric linear actuator includes include a housing, a puck, an actuator rod, and an electric motor. The puck is contained within the housing and configured for substantially linear motion, within the housing. The actuator rod is capable of being contained, at least in part, within the housing and configured to actuate, in a substantially linear fashion, in response to substantially linear motion of the puck. The electric motor is disposed within the rod and configured to provide mechanical force to cause the substantially linear motion of the puck, within the housing.

Electric powered linear actuator

An electric linear actuator is provided. The electric linear actuator may have a cylinder housing, an electric motor disposed inside the cylinder housing, a piston rod at least partially slidably disposed inside the cylinder housing, and a planetary gear arrangement disposed inside the cylinder housing and configured to connect the electric motor to the piston rod. The planetary gear arrangement may have a ring gear integrally connected to the piston rod. The electric motor, the planetary gear arrangement, and the piston rod may be disposed in series along a central axis of the cylinder housing.

Electric linear actuator having planetary gear arrangement

A method for assembling a spray pattern adjustment assembly for use with a spray head assembly is provided. The spray head assembly may define an outlet passage that has a height. The method may include the steps of inserting the spray pattern adjustment assembly having a reduced height compared to the height of the outlet passage into the outlet passage, increasing the height of the spray pattern adjustment assembly to at least match the height of the outlet passage, and substantially fixing the position of the spray pattern adjustment assembly relative to the spray head assembly.
