To suppress positional deviations of magnetic members of a stacked core and prevent damage thereto when the stacked core is attached to a case. A method for producing a stacked core including a stack of foil-shaped magnetic members for fixation to a case with a fastening bolt includes preparing magnetic members each having formed therein a positioning opening, and a tubular collar adapted to be fastened to the case with the fastening bolt inserted therethrough, the tubular collar having a first receiving face for a head of the fastening bolt and a second receiving face for the case, stacking the magnetic members while arranging the collar within the opening, impregnating gaps between the stacked magnetic members as well as gaps between the openings of the magnetic members and the outer peripheral face of the collar with resin, and integrating the magnetic members with the collar by curing the resin.

A spacer (1) is injection molded by using an injection molding die having resin flow channels that are designed such that a plurality of gates (6) are arranged along the longitudinal direction at a position corresponding to the outer peripheral surface of a side wall part (4) in which a plurality of arc-like peripheral surface parts (2) are connected through a waist part (3). After opening the mold and ejecting the spacer, the spacer is cooled with a runner (7) being connected to the gate (6), and thereafter, the runner (7) is cut off. As a result, when producing a water jacket spacer that is assembled to the inside of the water jacket and controls the flow of cooling water by injection molding, while producing with a high productivity without being affected by design constraints caused by draft angle, deformation in the post-molding cooling step is prevented.

A resin material is injection-molded using an injection mold in which a resin flow channel is designed so that a plurality of gates are provided along a longitudinal direction at a position corresponding to an inner circumferential surface of a spacer, to obtain a molded product, the spacer having a shape that a plurality of arc-shaped circumferential surfaces are linked through a constricted part. The molded product is cooled in a state in which a runner that is connected to the gates is allowed to remain, and the runner is cut off thereafter. A water jacket spacer is produced by injection molding while achieving excellent moldability, the water jacket spacer being disposed in a water jacket, and controlling the flow of a coolant, the water jacket spacer including a plurality of segments, or having a shape that the water jacket spacer can be partially inserted into the water jacket.

A cylinder head cover and a method for producing a cylinder head cover are disclosed. The method for producing a cylinder head cover may include: providing at least two metallic bearing bridges including a respective through-opening for mounting at least one camshaft and aligning the respective through-opening of the at least two bearing bridges axially relative to one another; connecting at least one metallic connection element to the at least two bearing bridges in a fixed manner so that the at least two bearing bridges are fixed and aligned relative to one another; and at least partially overmoulding the at least two bearing bridges and the at least one connection element with a plastic material.

A housing for a motor-transmission unit with at least two housing sections which have in each case at least one accommodation segment for receiving a motor and an internally-toothed, internal ring gear segment for receiving a gear of a planetary gear unit, wherein the housing sections can be or are connected with each other and wherein, in the assembled state, the accommodation segments of the housing sections together form at least one accommodation compartment for holding the motor, and the internal ring gear segments of the housing sections together form an internal ring gear for mating with a gear on the planetary gear unit.

A resin filling device includes: a first mold and a second mold provided so as to face each other to sandwich therebetween a laminated iron core and thereby to fix the laminated iron core; a flow path forming member provided to the first mold so as to be engageable with one of the axial ends of the laminated iron core and forming a resin flow path through which a resin flows; and a fitting member provided to the second mold to be fitted into an opening portion of the flow path forming member that is in communication with the resin flow path, wherein the fitting member is provided with a vent portion for discharging air in the resin flow path to outside.

Piece comprising a first metal part and a second part in organic matrix composite material, wherein the first part has a first connecting portion and the second part has a second connecting portion, the second connecting portion having at least one through-hole, the second connecting portion being totally or partially sandwiched between the first connecting portion and a metal fastening element, the fastening element being fastened on the first part both onto the first connecting portion via the through-hole of the second connecting portion and onto a portion other than the first connecting portion, whereby the first part and the second part are fastened to each other.

A media channel assembly for an internal combustion engine includes at least one distribution channel for distributing a medium to various components of the internal combustion engine, and at least one supply channel, which is coupled to the distribution channel by way of at least one media passage opening. At least a wall region of the distribution channel lying opposite the media passage opening is curved, at least in parts, toward the media passage opening. An internal combustion engine includes such a media channel assembly, and a motor vehicle includes such an internal combustion engine.

A stator for an electric motor is provided herein. The stator may include a stator body including a plurality of laminations, a plurality of wire windings, and winding end-turns formed by the wire windings. The stator may further include a polymeric composite housing disposed around at least a portion of an exterior surface of the stator body and a plurality of channels for heating and/or cooling the stator, which are defined in the polymeric composite housing. Methods of making the stator are also provided herein.
