Knee speed control valves, exhaust air controlling, internal screw

Working principle:

Throttle check valves throttle the flow rate in one direction, in the other direction the flow is unthrottled. The non-return valves are "exhaust air regulating" in the standard design. For example, if the valves are screwed into a cylinder, they ensure smooth running without a slip-stick effect. For cylinders with a small volume (small diameter/short stroke), the non-return valves are used in the special "supply air controlling" design.
