摘要： PURPOSE:To compact a relief valve by providing a pressure reducing function, a rotary driving force function and a fluid transfer function to the inside of a machine without injecting energy from the outside by using the relief valve having energy restoring mechanism which utilizes kinetic energy of flowing fluid. CONSTITUTION:A liquid flowing into the actuating valve 1 of a relief valve is allowed to pass through a convergent high speed tube 2 at the exit of the actuating valve 1 and is injected from an injection opening 3 into an outer tube 4 provided on the outer periphery. At the upper portion of the outer tube 4 an actuating tube 6 is continued to an intake chamber 5 provided outside the high speed tube 2 and an opening 7 is located inside the intake chamber 5. The intake chamber 5 is converted to a pressure reduced state by the flow speed of the liquid injected from the injection opening 3, and, when the actuating tube 6 is connected to a pressure switch, the pressure switch is actuated. Also, when the actuating tube 6 is connected to a specific liquid and/or gas, the liquid and gas can be absorbed and discharged from the outer tube 4 and so the quantity of the liquid and gas can be adjusted; or, when the actuating tube 6 is connected to a mechanism which particularly needs pressure reduction, pressure within the pressure reducing mechanism can also be adjusted.

摘要： PURPOSE:To enable gaseous foreign matters to be removed as well as rationally arrange various kinds of constitutional parts by means of a simple structure by arranging an oil lead-out tube in the central part of whirling flow in the oil lead-out passage around the peripheral part of the whirling flow. CONSTITUTION:Oil compressed and delivered by a pump P is introduced into a housing 1 through a check valve 22 and filtered through a filter element 5. Consequently, the oil made free of its solid foreign matters is introduced into a cyclone device 6 from an opening 12. That is, the oil is whirled by a swirl vane 13 and it comes to be a whirling flow in a whirling flow chamber 11. Then, the oil containing a great amount of gaseous foreign matters collected in the central part of the whirling flow is introduced into a lead-out pipe 10 through a through hole 15 and delivered to an oil pan or others through the first lead-out passage 20. On the other hand, the oil hardly containing gaseous foreign matters collected around the peripheral pat of the whirling flow is introduced into an air space R from the opening 12 and delivered to a lubrication part or others through the second lead-out passage 21.

摘要： PURPOSE:To make it possible to determine the quantity of gas incorporated in flowing liquid by measuring the density of the entire liquid incorporating the gas. CONSTITUTION:With respect to a transport line 1, the following parts are provided: a density measuring device 9, a pressure sensor 7, a temperature sensor 5, pressure operating circuits 8, a temperature operating circuit 6, a gas-content operating circuit 10, an operating panel 11 and a gas-content display panel 12. Data required for the operation of the content of gas are inputted from the panel 11. Liquid incorporating gas is made to flow through the transport line 1. After liquid pressure and liquid temperature are measured, density is measured with the density measuring device 9. The liquid pressure is measured once more at the outlet of the measuring device 9. The measured values are inputted into the circuits 8, 6 and 10, and operations are performed. Thus the gas content in the liquid is converted into the gas content under the reference temperature and the reference pressure, and the result can be displayed on the panel 12.
