Abstract

25,680. Oddie, P. F. Dec. 29. Pump valves and valve gear concussion, preventing. - The suction valve p is held down by a strong spring v, against which it is raised at the beginning of the suction s t r o k e by pressure acting on a plunger r connected to the valve and fitting in a cylinder s, this pressure. being reduced before the end of the suction stroke, so that the valve closes quietly. The invention is shown applied to a three-throw pump, where the pressure in one cylinder s is obtained from an adjacent pump chamber. The pressure may, however, be otherwise obtained and controlled by valves &c. operated from the pump shaft. The movements of the valves p are controlled by throttle valves u.
