    • The present invention is directed toward a filter head that is adapted to mount a filter between an upstream fluid supply and a downstream fluid pump such as might be used for an oil burner system that includes a combination of the filter head and the safety valve in a single unit that may be interposed at a location along an oil conduit. The filter head comprises a filter head housing having an inlet port and an outlet port and a filter mounting stub that is adapted to mount the filter thereto. The filter mounting stub provides a filter head entrance port and a filter head exit port fluidically between the inlet and the outlet ports for communication with the filter when mounted thereto. A safety valve is mounted in the filter head housing and is arranged fluidically between the inlet and outlet port of the filter head housing. The safety valve has open and closed positions and opens in response to vacuum pressure at the outlet port.
    • 本发明涉及一种过滤头,其适于在上游流体供应源和下游流体泵之间安装过滤器,例如可用于油燃烧器系统,其包括过滤器头部和安全阀的组合 可以沿着油管道的位置插入的单个单元。 过滤头包括具有入口和出口的过滤器头壳体和适于将过滤器安装到其上的过滤器安装短管。 过滤器安装桩在入口和出口之间流体地提供过滤嘴入口和过滤嘴出口,用于与过滤器连接时与其连接。 安全阀安装在过滤器头壳体中,并且流体地布置在过滤器头壳体的入口和出口之间。 安全阀具有打开和关闭位置,并响应出口处的真空压力打开。
