Abstract

The oscillator is operated by a fluid at high speed. Cavitation is prevented vented. Smooth operation and frequency stability are achieved by providing hoses having a resilient cylinder wall at the location where the fluid is applied.

Fluid Operated Oscillator

The oscillator is operated by a fluid at high speed. Cavitation is prevented vented. Smooth operation and frequency stability are achieved by providing hoses having a resilient cylinder wall at the location where the fluid is applied.

A two sectional piston comprising two rigidly connected individual pistons 11 and 12 is movably arranged within a valve body 13. Fluid of medium pressure m, low pressure 1, and high pressure h is supplied to valve body inputs 14, 15 and
16. At these inputs, resilient hose pieces R serve as connections between the inputs and the fluid sources. This makes the applied fluid effective at a faster rate. At the input 17, resilient hose 20 is closed at one end. The inputs 18 and 19 are connected by resilient tube 21.

In the position of the pistons 11 and 12, shown by full lines, they are forced to the right. This is due to the medium pressure m applied to the left surface of piston 11 and the low pressure 1 applied through tube 21 to the right surface of piston 12. Upon this movement, the pistons 11 and 12 assume the position shown in dotted lines. Input 16 is thus opened. High pressure h is now applied to the right surface of piston 12, thus forcing the pistons back again to its left hand position. A continuous oscillating movement of the two-sectional piston commences.
