FIELD: engines and pumps.
SUBSTANCE: design for erection of disc of pulse generator includes the following: key groove (14), key part (16) and fastener (18). Key groove (14) is made in end surface (10) of rotating wall (9). Key part (16) is provided on disc of pulse generator (P). Disc of pulse generator (P) is attached to rotating wall (9) by means of fastener (18). Key part (16) is made of arc-shaped band-like part (16a) and pair of connecting parts (16b). Arc-shaped band-like part (16a) protrudes in the bent shape from end surface of disc of pulse generator (P). Arc-shaped band-like part (16a) is engaged with key groove (14). Connecting parts (16b) provide connection between the disc of pulse generator (P) and opposite ends of arc-shaped band-like part (16a). Longitudinal directions of key groove (14) and arc-shaped band-like part (16a) are located along radius of disc of pulse generator (P).
EFFECT: development of design for erection of disc of pulse generator, at which high positioning accuracy and manufacturability is provided.
