A method for manufacturing a poppet valve or mushroom valve includes providing a mixture of metal powder and a binder, filling and pressing said mixture in a mold, to obtain a green product, removing the binder from the green product, and thermally sintering the green product to a poppet valve blank, by hot isostatic pressing. A poppet valve is also provided that is manufactured with this method.

Poppet valve and method of its manufacture

A internally cooled poppet valve () with inertial pump () includes a valve body () having a valve head () and a valve stem (). The valve body () has a closed cavity (), in which a cooling fluid () is disposed. The inertial pump () is disposed in the valve body (), which moves the cooling fluid () in the cavity during operation.

A method for the production for a semi-finished valve product (), includes casting, forging, deep-drawing, pressing and/or drop-welding of one or several metal material into a semi-finished valve product () that corresponds to a circle segment of a valve cut open in the axial direction. A valve is produced by welding together at least two semi-finished valve products () into an internally cooled valve, with the weld running in the axial direction of the valve.

Inside-cooled disc valve and a semi-finished product and method for its production

A poppet valve () with a valve body () has a cavity (), a coolant inlet port (). A coolant outlet port (). The coolant inlet port () and the coolant outlet port () are arranged on a valve stem () of the poppet valve (). The cavity () extends into the valve stem () of the poppet valve () and into a valve head () of the poppet valve (), wherein there is provided a coolant conducting element () within the cavity () and extending into the cavity () from the valve head () to the valve stem (), where the coolant conducting element () in each case has a cross-section. The coolant conducting element () includes a pipe section () and a funnel section (), and the coolant conducting element () extends concentrically to the poppet valve () in the cavity () of the poppet valve ().
