Sebastian GAJDA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A vane pump having an electric drive unit with a drive shaft, a pump chamber, a rotor arranged in the pump chamber so as to rotate about a rotational axis, and a driver that has at least one driver pin and is connected in a rotationally fixed manner to the drive shaft, wherein, in an operating state of the vane pump, the driver pin, by way of a contact surface of the driver pin designed as a section of a lateral surface, engages in a torque-transmitting manner with a contact surface of the rotor delimiting a rotor recess designed to correspond to the driver pin. In order to improve a vane pump, it is proposed that the contact surface of the rotor is designed and arranged in such a manner that the rotational axis lies in the contact surface when this contact surface is hypothetically extended toward the rotational axis.
