Title: Apparecchio a chiocciole co-rotanti con perfezionato accoppiamento per compressori o espansori di fluidi.
Inventor: UTTER ROBERT E
IPC: F01C1/02
Filed: 1991-11-08
Granted: 1995-03-30
Abstract: In un apparecchio a chiocciole co-rotanti avente due avvolgimenti di chiocciola interfogliantesi fissati a piastre di estremità che ruotano attorno ad assi paralleli non concentrici, per produrre un moto orbitale relativo, un accoppiamento per provocare la rotazione simultanea e per migliorare la stabilità nutazionale dell'elemento a chiocciola. Nella forma di realizzazione preferita, i mezzi di riduzione della nutazione sono costituiti da un accoppiamento di tipo Oldham che impegna organi di estensione su di una delle piastre di estremità della chiocciola e azionano chiavette sull'altra rispettiva piastra di estremità. La loro disposizione angolare è ottimizzata per far si che l'accoppiamento Oldham generi durante la rotazione un carico a momento moderante in opposizione al carico a momento di rovesciamento di almeno uno degli elementi a chiocciola e migliorando perciò la stabilità nutazionale degli elementi a chiocciola. Il carico a momento di moderazione dell'accoppiamento imposto sugli elementi a chiocciola può essere alterato variando la disposizione angolare e radiale del baricentro dell'accoppiamento.

Patent MX-163088-B (MX)
Inventor: GUTHRIE ROGER THACKSTON
IPC: D21F3/02
Filed: 1984-11-12
Abstract: A system for delivering controlled quantities of a stream of fluid to an application zone includes a positive displacement pump (100) comprising a piston housing (111) with an interior cylindrical wall (115). A pumping chamber (116) lies adjacent a closed end of the pump cylinder. A reciprocating and rotating piston (118) in the cylinder draws fluid into the chamber (116) and expels the fluid therefrom. A barrier fluid inlet (122) adjacent the piston (118) enables barrier fluid to be delivered to the cylinder at a pressure greater than the maximum fluid pressure in the pumping chamber (116) to preclude migration of pumping fluid along the piston to the opposite end of the cylinder.
