Benefits of technology

This patented technical solution described for making an improved type of metal slide valve used in refrigerant compression systems involves reducing the number of expensive components while maintaining their strength or durability over time without compromising their function effectively. Additionally, this new design allows for better lubricity between different parts during operation compared to traditional designs due to increased surface area provided through specific areas within these parts where they come into contact. Overall, this technology provides more efficient and effective cooling system improvements at lower costs than current options such as those made from special alloys like chrome steels.

Problems solved by technology

This technical problem addressed by this patented describes an improved design solution for improving the durable and resistant properties of compressed gas valve actuators used in vehicles' air conditionings systems. Current solutions involve expensive specialized alloys containing rare metals like cobalt chrome nickel, molybdenum, tantalum, tungsten, copper, iron, zirconia, ceramics, and other heavyweight substances. Additionally, current methods require complicated processes involving multiple steps including thermal spray treatments at different temperatures and pressures, leading to decreased production efficiency due to reduced cooling capacity during operation cycles.
