Abstract: There is disclosed a pressure regulating valve which effectively reduces a noise of a fuel pressure regulating valve without relation to a flow amount of a fuel. In this valve, a flow collision preventing member (35) is fitted to an upper end opening portion of a bush (26), and an upper portion of the flow collision preventing member (35) is protruded to a side of a valve body (33) rather than a valve seat (28) (an upper end surface of the bush (26)). A plurality of flow passages (36) for flowing the fuel in an axial direction thereof (in a downward direction) along an inner peripheral surface of the bush (26) are formed in an outer peripheral portion of the flow collision preventing member (35) with a uniform interval. A runoff recess portion (37) running off a protruding portion of the flow collision preventing member (35) is formed in the valve body (33) positioned immediately above the valve seat (28).

Abstract: A motorized rotary water valve has an integrally formed one piece motor housing and emergency bypass channel. A solenoid operated valve is integrally provided on the bypass channel and is spring biased to the open position upon shut off of electrical power to the solenoid.

Abstract: A bypass assembly is provided for bypassing a water softener. The bypass assembly includes a bypass valve, a shut off valve at the input to the water softener, and a shut off valve at the output of the water softener. The shut off valves are positioned between the bypass valve and the tank of the water softener. A t-shaped fitting is used to interconnect the water supply, bypass valve and first shut-off valve and a second t-shaped fitting is used to interconnect the water discharge port, the bypass valve and the second shut-off valve. The t-shaped fittings are provided with double street ends to facilitate interconnection of the t-shaped fittings to corresponding valves.
