    摘要: L'objet principal de l'invention est un système de compression passive (1) à piston (2) pour la compression d'un deuxième fluide (4) par la détente d'un premier fluide (3) comprimé, comportant : une enceinte fermée (E) ; un piston (2), mobile selon un axe de translation (T) ; une première chambre (5), destinée à contenir du premier fluide (3) comprimé ; une deuxième chambre (6), destinée à contenir du deuxième fluide (4) à comprimer. La première chambre (5) comporte des premiers moyens d'admission (10) du premier fluide (3), et des premiers moyens d'évacuation (11) du premier fluide (3). La deuxième chambre (6) comporte des deuxièmes moyens d'admission (12) du deuxième fluide (4), et des deuxièmes moyens d'évacuation (13) du deuxième fluide (4). Le piston (2) est configuré pour faire varier la pression dans la première chambre (5) et la pression dans la deuxième chambre (6) par déplacement en translation.

    摘要: An air motor has a source of pressurized air, two air chambers, a pilot valve and a directional control valve. The spool of the directional control valve is of the unbalanced type and includes a piston surface in continuous communication with atmosphere through an exhaust port and a pressurized restricted port in alternating communication with the large end of the spool and the piston surface. The alternating communication of the source of pressurized air through the restricted port is restricted relative to the continuous communication of the piston surface with atmosphere. At the point of shift of the directional control valve, the piston surface is in communication with the source of pressurized air through the restricted port.

    摘要: There is disclosed a pump, in particular a reciprocating pump. In one embodiment, a reciprocating pump (10) is disclosed which comprises an actuating cylinder (12); an actuating piston (16) mounted for reciprocating movement within the actuating cylinder; a discharge cylinder (52); a sleeve (40) releasably mounted within the discharge cylinder, to thereby define an operating diameter of the discharge cylinder; and a discharge piston (30) coupled to the actuating piston and mounted for reciprocating movement within the sleeve to successively draw fluid into and discharge fluid from the discharge cylinder. There is also disclosed a sleeve for such a pump, and a method of changing output flow from such a pump.

    摘要: In a pump employing a bellows, individual members are formed from resins and pump components including a fitted assembly formed by fitting plural members with each other form a structure unit which is tightly inserted in an external cover and constrained on the opposite ends thereof for come-off prevention. Thus, the distortion or deformation of the members during assembly is obviated and hence, a good sealing performance is achieved.

    摘要: A reciprocable device (11) comprising a reciprocable member (17) mounted for reciprocating movement within a chamber (15) and a valve system for controlling the supply of fluid under pressure to the reciprocable member to bring about reciprocation of the member. The valve system comprises a spool valve (43), a coupling mechanism for joining the reciprocable member and the spool valve, and a bistable spring, which is actuated by the reciprocable member (17), for driving the spool valve (43) through the coupling mechanism.
