'738 patent, col. 8 line 17) does not mean that the oil never flows through the spool valve on its way from the source as explained below, it clearly does. Rather, this statement means that oil does not flow along a central, longitudinal passage within the spool. This is confirmed by the remainder of the paragraph, which Hitachi crops. (See id. at col. 8 lines 16-19 ("engine oil flow path to the vane system . . . bypasses spool 200, that is, does not utilize a passage internal to spool 200 to supply oil to inlet line 182, as in previous systems" (emphasis added)). As shown below, oil must flow along the internal lands of the spool valve in order to reach the actuator:
fluid flow from source to vane housing
no fluid flow, in contrast to prior systems (i.e., this part of the spool is "bypassed")
As the original application claim 16 confirms, the "source of hydraulic fluid" is '230' (the MOG), and fluid flows from this source to the vane actuators (160a and 160b). (Orig. Spec. from the '738 patent prosecution history (Matterer SJ Decl. Ex. 2) at BW 002106 (claim 16)). The oil which comes from the main oil gallery is indisputably allowed and blocked by the
