    摘要: A mold cooling device comprising an air feeding/discharging circuit (22) for effecting the pneumatic drive of a pump section (1) which feeds cooling liquid to a fluid flow passageway (65a) formed in a mold (64), and the feeding of air to the fluid flow passageway (65a). Let Dx be the outer diameter-equivalent dimension of the perforated raised portion (53x) of a cast article (64x), D1 be the outer diameter of the pin portion (65) of the mold (64), t1 be the outer peripheral wall-thickness of the pin portion (65), and T1 be -5.103+(0.621xDx)-(1.068xD1)+(3.61xt1). Then the time T required for feeding the cooling liquid to the fluid flow passageway (65a) after completion of the flowing of molten metal into the mold (64) is set to satisfy the relation T1 -0.5 sec.

    摘要: There is disclosed a valve assembly for a pump such as a dual-piston reciprocating pump, and to such a pump incorporating a valve assembly.
    In one embodiment, a valve assembly (10) is disclosed which includes a valve main body (98); a valve member (100) mounted for movement within the valve main body, to control the supply of an actuating fluid to a pump (10); a main valve inlet (81) formed in the valve main body, through which actuating fluid is supplied to the valve main body; and an inlet valve (83) for controlling the flow of actuating fluid through the main valve inlet into the valve main body. Providing a valve assembly with such an inlet valve facilitates accurate control of the flow of actuating fluid into the valve assembly. This in turn facilitates control of the flow of actuating fluid to a pump, thereby permitting one or more operating characteristics of the pump to be varied.

    摘要: An assembly (12) for testing an evaporative emission control system (10) of an automotive vehicle which controls emission of volatile fuel vapors. The assembly is used to determine if a leak is present in a portion of the system which includes a vapor collection canister (14). The leak detection assembly incorporates a vacuum actuated canister vent control valve (32) which seals the evaporative system so the leak detection test can be performed. A vacuum actuated pump (28) performs a leak detection test. An engine control (26) initialize the pump by drawing air into a pump cavity and also closes the vent control valve (32). After the initialization period, the pump is activated to pressurize the evaporative emission control system. Once a control pressure is achieved, the cycle rate starts to drop off. If no leak, the pump will continue to pump at a rate that will be representative of the flow characteristics of the size of the leak. After the test has been concluded, the vent control valve (32) will unseal the system after the vacuum has been bled out through the orifice/check valve (31) that has been holding the seal during the test.

    摘要: Doppelmembranpumpe mit einem Zentralgehäuse (1), zwei koaxialen Produktkammern (6) im Zentralgehäuse, Saugventilen und Druckventilen für jede Produktkammer, zwei die Produktkammern gegen koaxiale Druckmittelkammern (8) abdichtenden Membranen (7), nach außen abgedichtet geführten Kolbenstangen (13), einer bügelförmigen, die Kolbenstangen der Membranen verbindenden Außentraverse (17) und einem Steuerblock (19) zum wechselseitigen Beaufschlagen der Druckmittelkammern mit Fördermedium mit einem durch die Membranbewegung betätigten Steuerschieber (20). Die Pumpe weist kürzeste, nur zwei Umlenkungen aufweisende Wege für den Förderstrom und nur statische Dichtungen auf. Sie läßt sich insgesamt aus Kunststoff herstellen und ist besonders geeignet für hochreine Produkte in der Halbleiterindustrie, Biotechnologie sowie in der Pharma-, Kosmetik- und Lebensmittelindustrie.
