DEFINITION

Classification: 192/87.16

(under subclass 87.15) Device wherein both clutches are actuated by the same pressure-receiving member or by pressure-receiving members that are secured together.

(1) Note. The actuator of the disclosures herein may comprise an enclosure divided into two chambers by a

relatively movable partition. Pressure is applied to one or the other of the chambers to cause the movement of the partition or the enclosure. If the partition is moved, it is the piston (i.e., pressure-receiving member) common to both clutch-actuators. If the enclosure is moved its interior end faces are effectively pistons, and since the "pistons" are rigidly connected together, the enclosure is the pressure-receiving member common to both clutch actuators.
