Product Description
Basic motor construction consists principally of a body, cover, drive cartridge and shaft. Rotary motion is developed in the cartridge, which principally consists of a ring, rotor, ten vanes and two pressure plates. The rotor is splined and mates with the output shaft, which is supported by a ball bearing in the body and a bushing bearing in the cover pressure plate. The vanes slide radically in the rotor slots and follow the elliptical cam contour of the ring as the rotor turns. These vanes are held against
the ring by a combination of spring and centrifugal forces.
Port connections are located in the body and cover. Direction of shaft rotation is governed by the direction of fluid flow through
these ports. Pressure is sealed from one port to the other by a Teflon sealing ring in the body on the periphery of the ring.
Drainage is ported through an external connection in the cover.
The cartridge is bolted together and can be serviced as a complete assembly. Locating pins position the ring with respect to the
pressure plates, and in like manner, two torque pins position the cartridge in the cover. The cover can be assembled in four
positions with respect to the body. Changing of the port positions is accomplished by rotating the cover and cartridge.
