Patent IT-1058151-B (IT)
Title: Fluid flow restrictor - has plug thrust against outlet in chamber by fluid flow against return force
Inventor: HANCE PIERRE
IPC: F16K17/20
Filed: 1976-04-16
Granted: 1982-04-10
Abstract: A moving plug is enclosed in a working chamber, in which there is an inlet (5) at one end inaccessible to the plug (8), and an outlet (2) at the other which it seals off when driven towards it by the fluid flowing from the inlet. A return force is exerted on the lug to thrust it clear of the outlet, typically by a return spring, or by the weight of the plug itself, or a magnet acting on the plug. The latter can be in the form of a ball smaller than the cross-section of the working chamber, so that fluid can flow between it and the chamber wall to the outlet. Alternatively it can be a hollow cylinder, working in a cylindrical section of the chamber, in whose wall the outlet is situated.

Abstract: A hydraulically damped automatic play compensation device for a motor vehicle clutch comprises a lever attached at one end to a clutch operating fork, and acting at the other end on a hydraulic damping cylinder which is axially slidable on a shaft, connected by a cable to a pedal lever and having a piston member with flow restriction means. Compensation for the play due to wear of the clutch is effected, between working strokes, by a displacement of the cylinder relative to the shaft which causes restricted flow transfer of an hydraulic fluid between two chambers in the cylinder and transmits the force of a subsequent working stroke directly to the lever maintaining the play compensating displacement of the cylinder.

Title: Endothermic 4-speed motor with a split cylinder and intercommunication valve
Inventor: LUIGI LILLIA
IPC: F02B/
Filed: 1989-01-12
Granted: 1992-06-30
Abstract: The invention is essentially made of a 4-speed motor in which the cylinder-piston-piston rod group is split, with everything on one elbow mast. The two chambers that are thusly formed are connected by an intercommunicating valve that opens only in the expansion and release phases. The result is, therefore, a motor that has a cylinder ventilation capacity equal to that of just one cylinder while the expansion and release work takes place in both groups. This provides for a greater combustible thermal exploitation than in a traditional motor while reducing both chemical and exhaust pollution.
