摘要： A piston and method is provided that inhibits the potential catastrophic damage to an internal combustion engine, thereby reducing the risk of costly damage to the engine. The piston includes a piston body having an upper combustion surface separated from an internal cooling chamber by a wall. The a pocket extends into the upper combustion surface to a closed bottom surface of the wall. A tubular member is disposed in the pocket. The tubular member extends upwardly from the upper surface. Should a valve head drop from its normal operating position, the valve head impacts the tubular member and forms a blow-by through passage extending from the upper combustion surface into the cooling chamber.

摘要： A hydraulically driven diaphragm pumping machine comprises a plunger (6) that is slidably mounted in a middle part of the inside of the machine's hydraulic cylinder (5) between first and second bellow-like diaphragms (4,10). Ends of the plunger (6) are connected to the first and second bellows-like diaphragm (10) to define respective first and second outer annular spaces (a) that are independent of one another, and the pressure of fluid in the first annular space (a) is independent of the pressure of fluid in the second annular space (a). The machine may also comprise a hydromechanical switch for commutating a valve (102) to automatically control the supply of hydraulic fluid to the hydraulic cylinder at given moments of the machine's cycle, comprising: a linkage (108,109) for converting linear motion of a piston (106) into rotary motion; a cam (103) rotatably driven by the linkage (108,109); and a spring (115) that is compressed to store energy by rotation of the cam (103) during a stroke of the piston (106), and arranged to release its stored energy to commute said valve (102) when the piston (106) is at given positions along the hydraulic cylinder (107). This commutation device also relates to any hydraulic cyclical working machine having a linear moving operating part and requiring to be automatically controlled via openings commutation in order to achieve desired working cycle parameters e.g. pressure values, cycle phases duration, etc.

摘要： The improved two-stroke internal combustion engine (1) with improved efficiency and reduced exhaust emissions comprises a crank mechanism (5, 6, 7, 8, 9), with a crank pin (7) and a connecting rod (8), the latter being connected to a guide piston (10) that moves up and down in a sleeve (11), and with a piston (20) connected to the guide piston (10). The piston (20) moves up and down in a cylinder (15) that is completely separate from the area of the crank mechanism (5, 6, 7, 8, 9), the latter being lubricated with oil that can be recycled. The piston (20) is substantially disc shaped and may comprise a plurality of cooling fins (20c). The lower part of the engine (1) may be used as a compressor to feed fresh air to the exhaust or to supercharge the engine, or as a pneumatic pump for direct fuel injection.

摘要： L'invention concerne un moteur hydraulique alternatif à piston différentiel interposé entre un conduit d'arrivée de fluide (6) ) à une pression P1 et un conduit d'échappement de fluide (14) à une pression (P2) inférieure à la pression (P1). L'ensemble mobile (9) constitué par les pistons (10, 11) de section différente qui coulissent dans un cylindre étagé (2) comporte un clapet (25) à deux positions et à trois voies, pivotable autour d'un axe de pivotement (24). Le clapet (25) est en appui dans chaque position sur deux portions de paroi (26, 27 ; 29, 30) disposées de part et d'autre du clapet (25) et de l'axe de pivotement (24) et non équidistantes de l'axe, de manière à créer un couple de fermeture positif par action des pressions (P1 et P2) sur les faces du clapet (25).

摘要： A fluid-driven reciprocating motor comprises a cylinder (2) and a displaceable piston (8) formed with a valve opening (20) therethrough and carrying a valve member (22) effective to close the vaJve opening (20) during the forward strokes and to open it during the return strokes. A stop (36) at the outlet end of the cylinder (2) is engageable with the valve member (22) at the end of the forward strokes to cause the valve member (22) to open the valve opening (20) to start the return strokes. The stop (22) includes a spring (34) effective, when engaged by the valve member (22) at the end of the forward strokes, to yield and thereby to store energy, which energy is transferred to the engaged valve member (22) at the start of the return strokes to maintain the valve member (22) in its open position for a short interval until the pressure in the inlet and outlet chambers (14,16) has been substantial- ly equalized at the start of the return strokes by the opening of the valve member (22).
