Abstract: A bobbin for a solenoid. The bobbin includes a main body for receiving wire windings of a wire, wherein the main body extends hollow-cylindrically along an axial direction and has a wall having a wall thickness, wherein at least one opening is formed in the wall, wherein the wall thickness becomes smaller along the axial direction toward the opening, and/or wherein the geometric shape of the opening is designed to vary along the axial direction, at least in sections. A solenoid having such a bobbin and at least one wire winding, is also described.

Abstract: An electromagnetic actuating device includes a pole sleeve that extends along an axial direction and an armature situated radially inside the pole sleeve. The pole sleeve has a first axial end and a second axial end. The armature is guided inside the pole sleeve. The pole sleeve has, in a region situated between the axial ends, recesses whose contours each change along the axial direction.

Abstract: A gear machine comprises a housing, at least two gearwheels positioned within the housing, and a bearing body defining a circular-cylindrical outer surface segment and a bearing bore. The at least two gearwheels configured to mesh in external engagement with each other. At least one of the gearwheels includes at least one bearing journal rotatably positioned within the bearing bore. The bearing body is positioned within the housing with the circular-cylindrical outer surface segment engaging a corresponding bearing surface defined on the inside of the housing. Each of the at least two gearwheels includes a plurality of tooth tips configured to engage a corresponding sealing surface defined on the inside of the housing. At least one segment of at least one of the sealing surface and the bearing bore is eccentric with respect to the circular-cylindrical outer surface segment of the bearing body. A method of production is also provided.
