A motion transfer device is provided for use in lubricating apparatus and systems. This device is for axial mounting on a pump having a rotating shaft. A diaphragm 17 is moved by reduced air pressure in space 16 and moves an inner housing 23 axially. Housing 23 cooperates with member 19 via balls 21 running in helical grooves in the housing and member. This member causes shaft 1 to rotate by use of a pawl and ratchet (14,15). Housing 23 is constrained to move axially by balls 24 rolling in axial grooves in the housing 23 and on part 29 (FIG. 1). |
