Abstract

681,893. Rotary pumps or engines. KLATTE, T. (trading as FIRMA T. KLATTE). June 25, 1951 [Sept. 7, 1950], No. 15054/51. Class 110(ii) In a pump or engine of the n and n + 1 lobe type, having a control valve 9 within the shaft, a chamber 15 diminishing in size is connected to one 16 increasing in size to prevent damage due to fluid being trapped. For a pump, the valve separates suction and discharge sides 12, 11. The pressure-relieving passage is formed by ducts 19, 20 and the size of a land 18 is greater than a land 10 to ensure sealing between the suction and pressure sides.
