A plasticizing device includes a rotor which has a groove forming surface provided with a groove, which rotates centering on a rotational axis, and a side surface of which is provided with a supply port communicated with the groove, a barrel which has an opposed surface opposed to the groove forming surface in a direction in which the rotational axis extends, and which is provided with a communication hole from which a material plasticized outflows, a heating unit configured to heat the material supplied via the supply port, and a housing configured to house the rotor, wherein the housing is provided with a first supply path and a second supply path configured to supply the material to the supply port.

The invention relates to a resin injection regulator for a resin injection circuit in a mould for producing a composite part, in particular a turbine engine composite part, characterised in that it comprises at least one vessel which is connected to said circuit and inside of which a movable wall means can be moved in a sealed manner, said movable wall means defining in said vessel a first cavity which forms a container for accumulation of resin and is designed to be connected to at least one part of said circuit, and a second cavity which is designed to be connected to a source of pressurised fluid, said movable wall means being designed to be urged by the pressurised fluid with which the second cavity is supplied in order to exert a pressure on the resin contained in the first cavity by isolating said resin from said fluid.

A plasticizing device includes a first flat screw including a first groove forming surface in which a groove is formed and configured to rotate; a second flat screw including a second groove forming surface in which a groove is formed and configured to rotate; a barrel including a first facing surface facing the first groove forming surface and a second facing surface facing the second groove forming surface and formed with a communication hole through which a plasticized material is fed outside; and a heating section configured to heat the material supplied to the grooves of the first flat screw and of the second flat screw.

An apparatus includes a first flow path member configured to define a first section of a flow path, a second flow path member configured to define a second section of the flow path, and a valve unit configured to suppress backflow in the flow path. The first section and the second section are connected via the valve unit. The valve unit comprises a displaceable valve body and a first valve seat portion. The first valve seat portion is configured to close the flow path in a case where the valve body abuts. The first valve seat portion is configured to abut on the first flow path member and is made of a material having higher hardness than that of a material constituting the first flow path member.

The plasticization device includes: a rotor rotating centered on a rotation axis by a drive motor and having a groove forming surface in which a first groove portion is formed along a rotation direction; a rotor case configured to accommodate the rotor; a barrel facing the groove forming surface and having a through hole; and a heating unit, in which a material supplied between the first groove portion and the barrel is plasticized by rotation of the rotor and heating by the heating unit to flow out from the through hole, and a side surface of the rotor has a material guiding port configured to guide the material to the first groove portion, and a second groove portion configured to feed the material supplied between the rotor and the rotor case to the material guiding port.
