    • A piston carrier (46) supports an elongated, slender piston rod (2) for reciprocation in a pump cylinder (30) to pump fluid into and out of the cylinder (30). The piston rod (12) is made of a material such as sapphire or zircon and has a diameter less than about ten millimeters, and the pump can provide flows of from about 50 nanoliters to about 250 microliters per minute at pressures of several hundred bars. A drive motor (18) rotates a threaded screw (58) and a drive nut (70) of a drive system (26) applies a linear drive force to the piston carrier (46). A ball and socket connection (74) between the drive system (26) and the piston carrier (46) avoids the need for precise alignment to prevent breakage of the fragile piston (12). A magnet (80) in the socket (78) holds the ball (76) in place and avoids the need for a spring or other mechanical holder. The socket (78) also includes a ring (88) of a low reluctance material surrounding the ball (76) to increase the magnetic retention force.
    • 活塞架(46)支撑用于在泵缸(30)中往复运动的细长活塞杆(2),以将流体泵入和泵出缸(30)。 活塞杆(12)由诸如蓝宝石或锆石的材料制成并且具有小于约十毫米的直径,并且泵可以在几百巴的压力下提供约50纳升至约250微升/分钟的流量。 驱动马达(18)旋转螺杆(58),并且驱动系统(26)的驱动螺母(70)将线性驱动力施加到活塞架(46)。 驱动系统(26)和活塞架(46)之间的球窝连接(74)避免了精确对准的需要,以防止易碎活塞(12)的损坏。 插座(78)中的磁体(80)将球(76)保持在适当位置并避免需要弹簧或其他机械支架。 插座(78)还包括围绕球(76)的低磁阻材料的环(88),以增加磁保持力。

    • The invention concerns a gas regulator (1) designed to be mounted on a supply duct connecting a gas source to an user appliance via a volumetric gas meter, said regulator comprising a heat-sensitive member (22) and an altimetric adjusting ring (26) for taking into account room temperature variation and atmospheric pressure variation related to altimetry, as well as a pressure regulating mechanism (13 to 15) controlled by the displacement of a mobile element (9). The invention is characterized in that it comprises a single prestressed adjustable actuator comprising a setpoint spring (12) interposed between the mobile element and a push rod (21) whereon are exerted stresses generated by the heat-sensitive member and the altimetric adjusting ring.
    • 本发明涉及一种气体调节器(1),其被设计成安装在通过容积式气量计将气体源连接到用户设备的供应管道上,所述调节器包括热敏元件(22)和高度调节环(26) 用于考虑与高度测量相关的室温变化和大气压力变化,以及由移动元件(9)的位移控制的压力调节机构(13至15)。 本发明的特征在于其包括单个预应力可调节致动器,其包括设置在可移动元件和推杆(21)之间的设定点弹簧(12),其中施加由热敏元件和高度调节环产生的应力。
