Abstract
The invention relates to a ball poppet valve having a valve body, a cylindrical valve bore disposed in the valve body, a ball poppet for closing the valve bore and a movable control stem intruding into the valve bore. The control stem acts on the ball poppet, and the control stem has a diameter (d) that at least approximately becomes larger and larger in the direction towards the ball poppet.
Claims17
A ball poppet valve comprising:
- a valve body, a cylindrical valve bore disposed in the valve body, a ball poppet for controllably opening and closing the valve bore and a movable control stem within the valve bore, to move the ball poppet, wherein the control stem has a diameter that increases along a longitudinal axis of the movable control stem in a direction toward the ball poppet.
A ball poppet valve, comprising:
- a ball poppet;
- a valve body that provides a valve bore;
- and
- a control stem configured and arranged to controllably move along the valve bore, where the control stem comprises a distal end and a proximate end where the distal end is located adjacent to the valve poppet and the control stem includes a first lengthwise segment located at the proximate end and having a fixed diameter and a second lengthwise segment that has a expanding diameter moving lengthwise along the control stem to the distal end of the control stem.

A ball poppet valve, comprising:
- a ball poppet;
- a valve body that provides a valve bore;
- and
- a control stem configured and arranged to controllably move along the co-axial valve bore, where the control stem comprises a distal end and a proximate end where the distal end is affixed to the valve poppet and the control stem includes a first lengthwise segment located at the proximate end and having a constant cross sectional area and a second lengthwise segment that has an increasing cross sectional area diameter moving lengthwise along the control stem to the distal end of the control stem.
