A hydraulic piston actuator, which may be used for an aircraft nacelle assembly, includes a housing, a piston, an end gland, and a bearing ring. The housing is concentrically disposed along an axis. The piston is adapted to axially reciprocate within the housing. The end gland is disposed radially between the housing and the piston. The bearing ring is disposed radially between the end gland and the piston.

A splined coupling assembly includes: a transfer gear having a first end, a second end opposite the first end, and a plurality of splines at the first end. The splined coupling assembly also includes a transfer housing having a first side, a second side opposite the first side, and a tubular portion located at the second side. The tubular portion includes a plurality of splines. The plurality of splines of the transfer housing are configured to mesh with the plurality of splines of the transfer gear. The splined coupling assembly further includes a shear ring located in a shear ring groove in the tubular portion- and a retainer configured to retain the shear ring within the shear ring grove.

Splined coupling

A check valve includes a housing, a first valve, and a second valve. The housing has a first portion that defines a first chamber and a second portion that defines a second chamber. The first valve is disposed within and is movable relative to the housing. The second valve is at least partially extends into the first valve. Responsive to a fluid flow in a first direction, the second valve and the first valve moves towards a proximal end of the housing and the fluid flow flows around the first valve towards a component.

An actuator assembly includes a housing, a piston rod, and an end gland. The housing defines a housing bore that extends along a first axis between a first housing end and a second housing end. The piston rod is at least partially disposed within the housing bore. The piston rod defines a piston bore that extends from a first piston end towards a second piston end along the first axis. The end gland has a first end gland surface that engages the piston rod and a second end gland surface that engages the housing bore. The end gland defines a first gland groove that extends from the first end gland surface towards the second end gland surface. The first gland groove is arranged to receive a self-lubricating filler that engages the piston rod. A self-lubricating bushing may also be provided to deposit a lubricant into the piston bore.

Actuator assembly having self-lubricating components

An actuator is provided for an aircraft engine and includes a tubular base layer and a visco-elastic layer adhesively disposed on the tubular base layer.
