    Abstract: The disclosure addresses a relief valve suitable for use in systems for delivering relatively viscous fluids. The described relief valve includes a housing and a valve mechanism moveable relative to an opening into the housing to allow or prevent flow from a flow path adjacent the relief valve into and through the housing. The relief valve is configured to minimize, and in many examples, essentially eliminate, a cavity between the housing opening and the adjacent flow path. Elimination of this cavity offers significant advantages as it minimizes or eliminates a location for pumped materials to accumulate and/or cure, which can lead to impairment or disabling of the relief valve operation.

    Abstract translation: 本公开涉及一种适用于输送相对粘性流体的系统中的安全阀。 所描述的减压阀包括壳体和阀机构，该阀机构可相对于进入壳体的开口移动，以允许或防止从邻近溢流阀的流路流入和穿过壳体。 安全阀构造成在壳体开口和相邻流动路径之间最小化并且在许多示例中基本上消除空腔。 消除该腔体具有显着的优点，因为其最小化或消除了泵送材料积聚和/或固化的位置，这可导致减压或禁用安全阀操作。

    Abstract: A fluid heater system for a pumping system comprises a core, a heating element and a sleeve. The core comprises a body made of thermally conductive material, and a plurality of channels formed on an outer periphery of the body. The heating element is disposed within the core. The sleeve surrounds the core adjacent the plurality of channels. The sleeve is formed of a material having a higher strength than the thermally conductive material of the core. In another embodiment, the plurality of channels is chamfered to form a portion of a common outlet plenum and the core includes a temperature sensor bore located proximate the common outlet plenum.
