    摘要: Pneumatic power tool comprises a housing (10) with a pistol type handle (11), a motor located in the housing (10), a pressure air inlet passage (13) and an exhaust air passage (14) both extending through the handle (11) in substantially parallel with each other, and a manually operable throttle valve (12) having two in sequence activatable valve elements (51, 53) for smooth starting and slow running of the motor, and a rotatable sleeve (40) for shifting between two positions corresponding to 'forward' and 'reverse' operation of the tool, respectively.

    摘要: A regulating valve for improving blocking function for a long period of time and capable of controlling a flowrate over a wide range. A partition wall (4) is provided in a valve main body (1) to partition an inlet flow path (2) from an outlet flow path (3), and an opening portion (5) for establishing communication between the inlet flow path (2) and the outlet flow path (3) is provided in the partition wall (4). A shut-off valve (10) is provided opposed to the opening portion (5) which is curvedly flared toward the shut-off valve (10). There is projectingly provided a control valve (12) positioned at the bottom end of the shut-off valve (10) on the flared side of, and coaxially with, the opening portion (5) and having a collar portion (12a) for defining an orifice (14) in cooperation with the inner peripheral surface of the opening portion (5). The shut-off valve (10) is vertically movable and has a bottom end surface (11) which can abut against a valve seat portion (15) formed around the opening portion (5).

    摘要: Die Erfindung betrifft ein Heißwasserventil, ins­besondere für eine Verwendung bei Getränkeautoma­ten. Es enthält ein Ventilgehäuse (3) mit einem Heiß­wassereinlauf (4) und einem Abflußrohr (5), wobei im Ge­häuse (3) ein Ventilkegel (11) mit einem Ventilsitz (7) zusammen­wirkt und wobei im Abflußrohr (5) eine Drosselein­richtung (13) zum Verstellen des Durchflußquerschnit­tes vorgesehen ist. Ein Ventilstößel (10) mitsamt dem von ihm getragenen Ventilkegel (11) ist von einer Dicht­manschette (12) aus am Ventilkegel (11) verdicktem, gummi­elastischem Dichtungsmaterial umgeben, und auch die Drosseleinrichtung (13) wird von einer rohrförmi­gen Manschette (12) aus gummielastischem Material ge­bildet, die tailliert ist und durch axiale Zusam­mendrückkräfte in ihrem Durchflußquerschnitt ver­änderbar ist. Kalkablagerungen in diesen Ventil­bereichen lassen sich auf einfache Weise durch Verformungen der Manschette (12) absprengen.

    摘要: A flow control valve includes a valve body with inlet and outlet ports, and an intermediate chamber therebetween. The valve further includes a static flow rate regulator for the fluid, accessible from outside the valve body and adapted to vary the cross-section of a passage orifice between the inlet and the outlet of the valve. The valve further includes a dynamic flow rate balancer, regulating flow rate based on a change of the incoming flow rate. The flow rate balancer includes a perforated element interposed between the inlet port and the intermediate chamber, allowing fluid passage only through at least one opening of the perforated element and an elastic element at one face of the perforated element facing the inlet port of the fluid into the valve body. An increase in the inlet/outlet differential pressure corresponds to an enlargement of the elastic element, guaranteeing a constant flow rate.
