Said system comprises a compressor (2), a heating body (3), a throttle element (4), and an evaporator (6), the compressor (2) having a variable stroke.

Provided is a fuel injection valve having a variable stroke mechanism.

The machine of the invention relates to a pellets press having a variable stroke length.

An internal combustion engine having at least one piston with an adjustable stroke length.

Either the fluid pump (22) and/or fluid motor (28) may be of a variable output design incorporating a cranskshaft (110) of variable stroke, adjustable on-the-fly.

A discharge displacement control system for a variable displacement compressor has control target setting means.

The push-on locating tool (12) may be operated by variable stroke pressure sensitive actuating means (23).

Also, the variable-stroke-type valve driver further includes a stroke adjustment hole for restricting the range of upward movement of the stopper, and a hole for fixing the stroke adjustment hole.

A variable stroke would match the rotor speed according to wind speed, functioning like a "variable-speed generator".

After experiments with this variable stroke windpump, research focused on wind-electric water pumping systems; no commercial variable stroke windpump exists yet.

The invention proposes a valve drive of an internal combustion engine with variable-lift gas exchange valve actuation.

The invention relates to a valve device for controlling the change of the stroke position of adjustable plate compressors such as wobble plate or swash plate compressors that have a variable displacement.

Said system comprises a compressor (2), a heating body (3), a throttle element (4), and an evaporator (6), the compressor (2) having a variable stroke.

The intake stroke draws ambient air into a variable volume chamber.

Provided is a fuel injection valve having a variable stroke mechanism.
