FIELD: engines and pumps.
SUBSTANCE: invention relates to propulsion engineering, particularly, to ICE fuel injectors. High-pressure pump for ICE fuel injection system incorporates at least one plunger pair with plunger which confines head end. Composite pusher is arranged between said plunger pump drive shaft. Said pusher comprises push element and bearing shoe fitted in element female seat part to support bearing roller. Said pushing element has centring guide for fitting bearing shoe in place.
EFFECT: higher reliability of accurate fit of bearing shoe in push element.
