Abstract
1. Насос высокого давления для устройства впрыскивания топлива в двигатель внутреннего сгорания, имеющий по меньшей мере одну плунжерную пару с плунжером (1), приводимым кулачком (2) или эксцентриком приводного вала в возвратно-поступательное движение и опирающимся опосредованно через толкающий элемент (3) толкателя и опорный ролик (4) на кулачок (2) или эксцентрик приводного вала, при этом предусмотрен опорный башмак (5) с в основном цилиндрическим углублением (6) для частичного размещения и охвата опорного ролика (4) в толкающем элементе (3) толкателя, отличающийся тем, что в основном цилиндрическое углубление (6) опорного башмака (5) образует с его торцевой поверхностью (8) продольные кромки (7), которые для размещения покрытия (9), проходящего от углубления (6) опорного башмака за их пределы, выполнены закругленными или с фаской.2. Насос высокого давления по п.1, отличающийся тем, что покрытие (9) предназначено для образования антифрикционного слоя и/или износостойкого слоя и предпочтительно выполнено из углерода или углеродного соединения.3. Насос высокого давления по п.1, отличающийся тем, что по меньшей мере одна выполненная закругленной или с фаской продольная кромка (7) расположена с радиальным отступом от опорного ролика (4), вследствие чего в поперечном сечении профиль в основном цилиндрического углубления (6) опорного башмака (5) по меньшей мере на отдельном участке отличен от профиля опорного ролика (4) в его поперечном сечении.4. Насос высокого давления по п.1, отличающийся тем, что опорный башмак (5) снабжен защитной накладкой (10), которая закрывает по меньшей мере часть его торцевой поверхности (8) и проходит за пределы по �1. A high pressure pump for injecting fuel into an internal combustion engine having at least one plunger pair with a plunger (1) driven by a cam (2) or an eccentric of the drive shaft in a reciprocating motion and supported indirectly through a pushing member (3) a pusher and a support roller (4) to a cam (2) or an eccentric of the drive shaft, while a support shoe (5) is provided with a generally cylindrical recess (6) for partial placement and coverage of the support roller (4) in the pushing member (3) atelier, characterized in that the generally cylindrical recess (6) of the support shoe (5) forms longitudinal edges (7) with its end surface (8), which, to accommodate the coating (9) extending from the recess (6) of the support shoe behind the limits are rounded or chamfered. 2. A high pressure pump according to claim 1, characterized in that the coating (9) is intended to form an antifriction layer and / or a wear-resistant layer and is preferably made of carbon or a carbon compound. A high pressure pump according to claim 1, characterized in that at least one longitudinal edge (7) made with a rounded or bevelled is radially indented from the support roller (4), as a result of which the profile of the generally cylindrical recess (6) is in cross section the support shoe (5) is at least in a separate section different from the profile of the support roller (4) in its cross section. The high-pressure pump according to claim 1, characterized in that the support shoe (5) is provided with a protective pad (10) that covers at least part of its end surface (8) and extends beyond
