(under the class definition) Apparatus including a means provided for the function of supplying lubricant to relatively moving parts of the motor (e.g., piston, transmission elements, etc.), said lubricating means requiring the actuation of a movable motive fluid control or distribution means.
(1) Note. Merely turning on a motive fluid supply valve, or actuating a distributor to supply motive fluid to the motor will inherently supply lubricant since motive fluid ordinarily carries out a lubricating function, and as such is excluded from this subclass, even if a separate means to
entrain another material in motive fluid solely for lubrication is provided, unless said motive fluid supply or distribution means separately controls the supply of separate lubricant material, or plural actuation of said supply or distribution means is required to properly carry out the lubricating function.
