Title (EN) APPARATUS GENERATING A RECIPROCATING MOTION
(FR) APPAREIL GENERANT UN MOUVEMENT ALTERNATIF
Abstract: front page image
(EN)The apparatus can be used in several applications, for instance for a pump, an engraving pen. Most apparatuses of this type call for precision-manufactured parts and consequently are expensive to manufacture. Other disadvantages of certain prior art apparatuses of this type is that they are difficult to start. The present invention is based on the insight that the surface of the part (1) performing the stroke motion must be small during the compression stage of the work stroke and large after the compression stage.
(FR)L"appareil generant un mouvement alternatif peut etre utilise dans plusieurs applications, par exemple pour une pompe, une plume de gravure. La plupart des appareils de ce type exigent une grande precision de fabrication et par consequent sont couteux. D"autres desavantages de certains appareils de l"art anterieur de ce type resident dans le fait qu"ils sont difficiles a mettre en route. La presente invention se base sur l"idee que la surface de la piece (1) effectuant le mouvement de la course doit etre petite pendant la compression de la course de travail et grande apres la compression.
