Abstract
A reciprocating piston and cylinder apparatus with adjustable stroke volume. The apparatus comprises an axially displaceable traveling cylinder, a stationary piston, and an optional sleeve secured to the traveling cylinder in a detachable manner. The traveling cylinder is displaced along its axis by a thrust component and acts cooperatively with the stationary piston to create a pressure change within the housing.
Claims8
A reciprocating piston and cylinder apparatus with adjustable stroke volume comprising:
- a. an axially displaceable traveling cylinder secured to a thrust component for receiving reciprocating thrust;
- b. optionally, a sleeve detachably secured to the traveling cylinder;
- and
- c. a stationary piston comprising a piston head and a piston shaft fixedly positioned concentrically within the traveling cylinder and in mechanical communication with the sleeve, if used or in mechanical communication with the traveling cylinder;
- and
- wherein the sleeve, if used and the stationary piston are configured to be removed and replaced to adjust a stroke volume of the reciprocating apparatus without detaching the traveling cylinder from the thrust component.
