Title: AC dynamo electric motor rotor resonant frequency modifier
IPC: H02K3/24
Filed: 1984-10-20
Abstract: The flutes concentrate contact forces generated by shrink-fitting in known positions and the non-contacting regions aligned with the flutes provided a small amount of resilience which permits thermal expansion of the rotor to occur without forcing a migration in the shrunk-fit contacting surfaces. The flutes may be used as axial ventilation holes whose effectiveness is enhanced by radially directed air flow channels communicating between the flutes and the outer surface of the rotor. - In rotors using laminations which include keyways the fluted shaft provides sufficient keying of the lamination to the shaft so that a key may be omitted. In order to avoid stacking of burrs in the laminations, succeeding groups of laminations are angularly indexed so that the effects of any recurring burrs are distributed about the circumference of the rotor and are cancelled out.

Patent ES-8606150-A1 (ES)
Title: Variable displacement pump system.
IPC: F04B1/30
Filed: 1985-02-01
Abstract: A variable displacement pump has a swashplate controlled by a pair of pistons. A shuttle valve communicates the highest pressure pump workport to an operator-controlled displacement control valve. A pressure-responsive override valve is connected in series between the displacement control valve and the pistons. When an override pressure is achieved, the override valve blocks communication of the control valve with the pair of pistons and communicates the pump workports directly to the pistons for rapid destroking. A neutral bypass valve is formed out of a sleeve of the displacement control valve to bypass control pressure to sump when the displacement control valve is in neutral. A pressure-reducing valve limits the pressure acting on the stroke control valve to limit response rates and reduce erosion. The override valve includes orifices which, in intermediate positions, provide flow rate control of the fluid flow to the swashplate control pistons.
