| An apparatus for preventing sudden changes of pressure in an air conditioned or ventilated vehicle, the vehicle comprising: an inlet orifice (3) for outside air and an outlet orifice (5) for inside air, the inlet orifice being connected to an intake duct (2) directing the air taken in to an air conditioning or ventilation system, the outlet orifice being connected to an exhaust duct (4) exhausting the inside air to the outside; shutter means (6, 7) for the intake and exhaust ducts (2, 4); a control member (14) receiving signals from the detector; and detector means (16, 17) for detecting the pressure outside the vehicle Po and the pressure inside the vehicle Pi and delivering signals representative of the pressure wave. | ||||||
| 22 | Process and apparatus for regulating the supply of fresh air in high-speed trains | US195517 | 1994-02-14 | US5462481A | 1995-10-31 | Hans J. Riedel; Michael Schmerler |
| A process and apparatus for regulating the quantity of fresh air in high-speed trains by means of pressure-wave valves. A signal for adjusting a drive unit is determined from the passenger count and outside temperature. This drive unit causes a stop fork to move into a flap stop position of the valve in the "open" operating mode so that the required amount of fresh air can be supplied. The process according to the invention results in a considerable saving on energy, since only the absolutely necessary amount of fresh air need be heated or cooled and the period of time in which ventilation can be used rather than cooling is lengthened. | ||||||

| 25 | Quick-acting gate valve | US150470 | 1993-11-10 | US5351933A | 1994-10-04 | Bernhard Schonks |
| The present invention is concerned with a quick-acting gate valve for installation on intake and exhaust openings of ventilation systems, in particular, of rapid railway vehicles, comprising a frame containing at least one passage slot provided with an adjustable closure element which relative to the passage slot can be placed into closed and open positions by a servo drive controlled in response to air pressure. In order to permit actuation of a quick-acting gate valve of this type substantially in a friction-free manner during opening and closing, the valve, in the practice of the invention, is so designed that the edges laterally confining the at least one passage slot relative to the in-flow direction are of a convex curvature. Behind the edges, the closure element is designed and arranged in the form of a similarly convex yet lesser curved leaf spring, the length of which corresponds at least to the length of the convex-curved edges of the passage slot. One end of the leaf spring is held on the frame while the other end thereof is displaceably guided on the frame. | ||||||
| 26 | Device and method for adjusting internal pressure of ventilated closed space receiving change in external pressure | JP19754297 | 1997-07-23 | JPH1071950A | 1998-03-17 | GERVAIS YVES; MARIAUX GILLES; MINEAUD GERARD; GUINOT ALAIN; ANDRE PIERRE |
| PROBLEM TO BE SOLVED: To observe a comfortableness criterion for a user by providing compensating circuits to adjust an air taking-in flow rate and an extracting flow rate in real time, and keeping internal pressure in a space on a constant level by algebraically compensating a leakage flow rate with a difference in a flow rate in an adjusting device of internal pressure of a ventilated closed space receiving a change in external pressure. SOLUTION: Compensating circuits 5 and 6 have a ventilator 10 and a control mechanism 11 of an instantaneous flow rate. An adjusting system 12 imparts an operation signal to operation mechanisms 14 and 15 to drive a control mechanism 11 in real time by using a signal outputted from a pressure sensor 13. An external sensor is added to anticipate the action on turbulence caused by a change in external pressure Pe by measuring pressure Pi of a space. A difference between an air taking-in flow rate q1 and an extracting flow rate q2 algebraically compensates a leakage flow rate qf, and the pressure Pi is maintained in reference pressure or preset pressure. Therefore, while reliably replacing air in a space 1, the pressure Pi of the space 1 can be maintained on a level close to a stored reference value. | ||||||

| PURPOSE: To achieve air exhaust from and pre-load into a cabin with a single axial-flow blower driven by a motor, by conducting switching between forward and reverse rotational direction of the blower for air suction and exhaust. CONSTITUTION: Grids 4, 5 are fitted at the ceiling pat of a cabin 3, ducts 6, 7 are connected to a conduit 8, and an axial-flow blower 1 is fitted on a jacket 9 at the end part of the conduit 8. The axial-flow blower 1 can be switched between forward and reverse rotational direction of the blower by a motor 2. By the axial-flow blower 1, the air from the cabin 3 is exhausted ((a) and (b) directions) to ventilate the inside of the cabin 3. By changing the rotational direction of the axial-flow blower 1 or to the contrary, supplying ((r) and (s) directions) air to the cabin 3 interior, pre-load is conducted for the cabin 3 interior. Switching the rotational direction with the single blower enables the air ejection from and pre-load into the cabin with a simple structure. COPYRIGHT: (C)1989,JPO | ||||||

| The pressure control system includes a detector (16) sensitive to variations in the external pressure around a vehicle. Conduits for the entry of air (2) and the exhaust of air (4) includes shutters (6,7) to control the flow of air in or out of the vehicle. A control unit (14) closes the shutters to reduce the rate at which the pressure changes within the vehicle, until the pressure difference falls to a certain level. The pressure inside and outside the vehicle is thus balanced, after a suitable control period. A diversion channel (17) maintains the variation of internal pressure below a set level, by circulation of air flow between the interior and exterior of vehicle, to balance internal and external pressure. | ||||||

| PROBLEM TO BE SOLVED: To reduce a micro atmospheric pressure wave during high speed travel without reducing cross sectional area of a car body leading to drastic reduction of the number of passengers. SOLUTION: A railway vehicle comprises an air intake means 6 provided to a nose portion of a leading vehicle 1, an air tank (reservoir) 9 for storing intake air, and an air outlet 11, by which air is sucked in (breathed in) during entry of the leading vehicle to a tunnel and discharged within the tunnel, so as to reduce the pressure generated at the nose portion and to cut down micropressure waves. When the nose of the leading vehicle 1 enters the tunnel 3, an intake control valve 8 of the air reservoir depressurized to below atmospheric pressure (1 atm) opens to take in air through an air inlet 6 via a path 7 into the air reservoir 9. When the whole leading vehicle enters the tunnel, the intake control valve 8 closes, and air is discharged through the outlet 11 via a pump 10. COPYRIGHT: (C)2005,JPO&NCIPI | ||||||

| The enclosed space (1), e.g. a rail carriage, has ventilation ducts (5, 6) carrying inward (q1) and outward (q2) air-flows, differing by a quantity (qf) representing leakage. Each duct contains a fan (10) and an adjustable (14, 15) flow-control device (11). An internal pressure (P1) sensor (13) inputs to a regulator (12) operating both flow-control actuators (14, 15). A memory (16) records a selected reference pressure. Above this pressure, the regulator reduces the in-flow, leaving the out-flow duct open; below, the out-flow, only, is reduced. The regulator ensures, in real time, that the difference between instantaneous flows continually compensates for leakage, keeping the internal pressure constant. Optionally, separate compensating ducts are provided, parallel to the main ducts. | ||||||
