    • 955,288. Valves. A. W. WOOD. Sept. 7, 1962 [Sept. 7, 1961; June 13, 1962; June 15, 1962; July 19, 1962], Nos. 32184/61, 22682/62, 23144/62 and 27822/62. Heading F2V. [Also in Divisions F4 and G3] A safety control means comprises a valve 8, fluid pressure means 9, 10 controlling the valve, an enclosed space 11, 12 surrounding a conduit 6 to be protected and connected to the fluid pressure means, and means 19 for establishing in the enclosed space a pressure different from that in the ambient atmosphere and in the conduit 6 to open the valve, the arrangement being such that on removal of the pressure differential the valve is automatically closed. In the preferred embodiment, the valve 8 consists of a rubber diaphragm normally held off the top of a pipe 5 by reduced pressure in a cylinder 9 and which is connected by the space 11, 12 and a chamber 15 to a suction bulb 19. When the chamber 15 is tilted to a predetermined angle a member 17 either topples off the chamber or falls about a hinge to allow air to enter an inlet 16 and the valve 8 to close. The member 17 may also be caused to uncover the inlet 16 by engagement of a pin 26 with a float arm 23 if liquid rises to an excessive level in a chamber 13 containing a second float-operated valve 21 controlling the outlet of the conduit 6. The latter and an outer conduit forming the space 12 may be of polyethylene or polypropylene to allow an oil burning appliance of the radiant or convector type on which the chamber 13 is mounted to be moved about. Closure of valve 8 also occurs if either conduit is fractured or the float arm 23 is operated manually by a lever 29. The valve 8 may be loaded by a spring or be replaced by a needle valve connected by a linkage to a barometric capsule.

    • A safety device for an oil burner includes a pump which has a drive cylinder portion with a double-acting piston movable therein which is connected through a connecting rod to a suction piston portion which is movable in a suction portion of the pump cylinder. The oil burner is supplied with fuel oil from a supply line having a shutoff valve or valves which are connected through a suction line to the suction part of the piston. The suction portion is connected through a check valve to a return line and the drive cylinder is connected on respective opposite sides of the piston through valve means for regulating the movement of the drive piston so that it moves after the burner is turned off to displace the suction piston to effect a suction on the supply line to the oil lance of the burner so as to withdraw the oil therefrom.
    • 一种用于油燃烧器的安全装置包括一个泵,该泵具有一个驱动缸部分,其中可以在其中活动的双作用活塞通过一个连杆连接到一个可在泵缸的抽吸部分移动的抽吸活塞部分。 油燃烧器从具有截留阀的供应管路供应燃料油,阀通过吸入管线连接到活塞的吸入部分。 吸入部分通过止回阀连接到返回管线,并且驱动气缸通过阀装置连接在活塞的相应相对侧上,用于调节驱动活塞的运动,使得其在燃烧器关闭之后移动以移动 抽吸活塞,以对燃烧器的油枪的供给管线进行抽吸,以从其中抽出油。
