A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly comprises an elongate conduit having a longitudinal fuel passage therein, a fuel inlet pipe, and a plurality of sockets. Outer walls of the conduit include at least one flat or arcuate flexible first absorbing surface, which is smoothly and integrally connected to an arcuate second absorbing surface. The first absorbing surface or the second absorbing surface faces fuel inlet ports of the sockets. The sectional configuration of the conduit can be flat, a telephone receiver shape, a character &ldquo;T&rdquo; shape, a corrugation shape, a dumbbell shape or a reverse eye mask shape. Thus, fuel pressure pulsations and shock waves are reduced by abrupt enlargements of fuel passages and bendings of the absorbing surfaces.

A temperature control device for a constant temperature chiller unit or a vending machine is provided. Thermal medium fluid such as water in the chiller unit is accurately controlled under starting mode, heating mode and cooling mode. Thermal medium fluid such as air in the vending machine is conveniently controlled in winter mode and summer mode. In the device, a heat exchanger is interposed within a compression circuit, and a bypass circuit is disposed at the downstream side of a pump so that through the bypass circuit thermal medium fluid receives heat from the heat exchanger. Thus, the temperature of thermal medium fluid supplied to an external secondary heat load is controlled.
