Modular valve for internal combustion engines to control the passage of gases or other aggressive fluids through an aperture in temperature environments from 40 C. to 700 C., said valve having several parts in stacked layers, that it has at least 2 parts wherein: the at least one core component (1) has a thickness (0.02 mm to 0.05 mm) much less than the thickness of the support plate (2) (0.05 mm to 2.0 mm), and the at least one core component (1) and the at least one support plate (2) are attached, and the at least one core component (1) has the remaining dimensions higher than those of the at least one support plate (2a, 2b), in order to form a protruding edge (1r) which will deflect in the contact area with the wall of the opening (5) when pressed against the wall of the opening (5) thereby increasing the valve closing angle.

A method to manufacture a throttle valve for an internal combustion engine comprising a valve body having a seat and a tube for the passage of conditioning fluid; an actuating device, which controls the rotation of a throttle plate; and a substantially uniform layer of a structural and heat-conducting resin interposed between the seat and the tube and applied on the entire available surface of the seat; the method comprising the steps of manufacturing the valve body provided with the seat by causing a first metal material to undergo a die casting process; applying a trace of the structural and thermosetting resin on the bottom of the seat; and inserting the tube into the seat so as to obtain a substantially uniform layer of the structural and thermosetting resin, which is interposed between the seat and the tube.

A throttle valve for an internal combustion engine provided with a valve body, a tubular feeding duct defined in the valve body, a throttle plate, and an actuating device which controls rotation of the throttle plate. The actuating device includes an electric motor and an actuating device conditioning circuit defined in the valve body. The conditioning circuit includes a tube made of a first material able to conduct heat, and the valve body is entirely made of a second metal material and is provided with a seat for housing the tube, in which is provided a layer of a structural and heat-conducting resin, interposed between the seat and the tube.

A modular valve unit for controlling the flow rate of an intake or exhaust gas of a combustion engine through the passage of a valve, the valve unit comprising a valve having a valve housing (1) and at least one valve flap (2). The valve unit further comprises an interface (3) and an adapter (6), the interface (3) being connected to the valve housing (1) and having a support (32) and an engagement portion comprising at least two engagement legs (31) projecting from the distal end of the support (32) and being directed away from the valve housing (1). The adapter (6) has a connection plate (62) having at least two engagement orifices (61) for receiving the engagement legs (31) of the interface (3) and a mounting portion for holding an actuator (7). The at least two engagement orifices (61) of the connection plate (62) of the adapter (6) are each configured to engage the corresponding at least two engagement legs (31) of the engagement portion of the interface (3).

Methods and systems are provided for an at least partially insulated throttle valve. In one example, a system may include a throttle valve having a first side configured to contact intake air flow and a second side configure to contact exhaust gas recirculate flow, where at least a portion of the second side comprises thermally insulating materials.
