Number: 91/318
Name: Motors: expansible chamber type > Cyclically operable > Working member controlled motive fluid for distributor motor > Motive fluid build-up at end of working stroke reverses distributor
Description: Apparatus in which the reaching of the terminus of a stroke of the output motor working member results in increase of pressure in the working chamber due to continued supply of motive fluid without working member movement, the increase of pressure in the working chamber causing the distributor motor to shift the distributor to reverse the direction of movement of the output motor working member.
