2 results about "Volumetric efficiency" patented technology

A high-pressure tank in which a liner can be formed using the conventionally used material, a decrease in the volumetric efficiency within the liner can be suppressed, and influence of a temperature rise due to adiabatic compression on the liner can be significantly alleviated. The tank includes a liner that suppresses permeation of gas; a valve device that allows the inside of the liner and the outside of the tank to communicate with each other and blocks communication therebetween; and an inner container with a through-hole disposed within the liner such that a gap is formed between the inner container and an inner periphery of the liner. The first communication channel of the valve device connects with a pipe extending in the gap and having holes therein. Gas supplied to the valve device is supplied into the gap from the holes in the pipe, and fills the inner container in a high-pressure state from the gap through the through-hole in the inner container.

The invention relates to a primary and secondary check valve group of an ultra-high pressure water generator. The check valve group comprises an ultra-high pressure water outlet joint body, a water outlet check valve, a water inlet check valve, a left-hand thread pipe pad, a connecting nut, an ultra-high pressure tee joint body, an ultra-high pressure water tank cylinder, a plunger, a water inlet joint body, a flared water inlet nut, a flared water inlet pipe sleeve, a low-pressure water inlet copper pipe and the like. In the invention, a two-grade dual sealing way is adopted, so that the positive conduction and reverse stop of ultra-high pressure water under an ultra-high pressure can be guaranteed effectively; and the opening and closing actions of a valve core are smooth and quick and the time response speed is high, so that the building of the ultra-high pressure of the whole system can be guaranteed and relatively high volume efficiency and relatively high power utilization rate of an ultra-high pressure water generating system can be guaranteed. Therefore, the check valve group is of important significance for the working performance and working reliability of an ultra-high pressure water mist generating system.
