Abstract

381,054. Conveying lubricant by fluid. SULZER FRERES SOC. ANON., Winterthur, Switzerland. Jan. 28, 1932, No. 2545. Convention date, Aug. 17, 1931. Addition to 330,818, [Class 12 (iii), Lubricators, &c.], and 341,799. [Class 12 (iii).] The invention described in the parent Specification, as modified by Specification 341,799, is further modified by the provision of means for regulating automatically the sectional area of the refrigerant vapour inlet nozzle of the injector to maintain the vapour velocity through the injector and, consequently, the flow of lubricating oil through the pipe d connected to the oil separator. The flow of vapour through the inlet nozzle a of the injector is regulated by a needle valve g secured to a spring-loaded piston k connected by a flexible sleeve h to the injector cover and subjected on its upper side to atmospheric pressure through a passage f<1> and on its lower side to the pressure of the vapour admitted through the pipe c from the evaporator. In a modification, the upper side of the piston k is subjected through a second piston to the pressure in the condenser. In a further modification, the upper side of the piston k is subjected to the pressure in the oil pipe d. In another arrangement, the needle valve g, Fig. 4, is regulated through link mechanism by the expansion or contraction of a flexible sleeve connected to a piston w and to the casing of the injector, the space within the sleeve communicating through a pipe u with a thermostat affected by the temperature of the evaporator.
