Latest Patents

One of Graf's latest patents is a motorised fluid metering valve. This valve features an inlet pipe, a discharge pipe, and a motor that moves a piston. The piston can transition between a closed position, where it sealingly engages with a seat, and an open position. The design allows for a continuously varying flow rate based on the axial position of the piston. The inlet pipe is strategically positioned to maintain a constant protuberance, ensuring efficient fluid flow without extending radially beyond the barycentre of the discharge pipe. Additionally, the motor employed is a rotary electric motor that facilitates the linear movement of the piston.

Another significant patent is for a positioning actuator. This actuator comprises a stator assembly, a rotor, and a printed circuit equipped with electronic components. It also includes a reduction gear for driving a rotary member. The actuator is designed with two complementary blocks. The first block consists of a shell with high thermal conductivity, housing the reduction gear and featuring a passage for the output shaft. The second block is formed by overmoulding the stator assembly and includes a rear bearing recess for the rotor. The electronic circuit is strategically positioned within the space defined by the two blocks, enhancing the actuator's functionality.
