Definitions
- Such high pressure valve arrangements are known wherein a central body carrying the valve is provided with an axial channel or bore cooperating with the delivery valve and, round said axial channel or bore, with sloping channels leading to the suction valve. Said sloping channels connect an annular chamber inside which the suction pressure prevails and which surrounds the central body with the seat of the suction valve.
- valves of such a type intended for pumps and compressors operating under service pressures which may reach several thousand atmospheres the material forming the different parts of the valve elements is subjected to stresses which are much higher than the stresses which are generally allowed in the execution of machines under conventional pressures.
- the constant modifications in the value of the pressure during the suction and compression strokes produce, in particular in registry with the sharp ridges and acute angles in the fluid conveying channels in the valve arrangement, load peaks which may lead readily through excess straining to breakage. It is possible to reduce such stresses by suitably rounded connecting surfaces and by machining the sharp ridges, but it is impossible thus to cut out completely the stresses.
- the present invention has for its object a coaxial suction and delivery valve arrangement operating under high pressures, wherein the detrimental action of the variations in stresses and consequently the shearing efforts, in particular as concerns the channels formed in the central body of the valve-carrying arrangement, are considerably reduced while the risk of breaking after a certain time is cut out to a large extent.
- the outer periphery of the central body extending between the packing which is to make the central body fiuidtight with reference to the valve casing and the seat of the suction valve and including the sloping channels, is subjected to a constant suction pressure over a length substantially equal to the length of the central passage or channel subjected to the varying pressure prevailing in the cylinder.
- the present invention also provides, according to a further advantageous feature, a reduction in the shearing action by giving the surface ensuring fluidtightness with the annular suction valve a part-spherical shape, whereas the bearing surface forming an extension of said spherical surface of the central body is urged under pressure against a ring constituted by a material having a high modulus of elasticity.
- the arrangement illustrated forms an assembly of coaxial suction and delivery valves for high pressure compressors and pumps.
- the fluid passes during the suction stroke of the piston into the cylinder bore 4 through the sloping channels 2 arranged in the central body 1, said channels2 being distributed round the axial channel 3.
- the fluid passes through the axial channel 3 in the central body.
- the fluid passing out of an annular chamber 5 formed in the valve casing subjected to the suction pressure and surrounding the central body 1, enters the sloping passages or channels 2 so as to reach the seat 7 of the member 8 forming the suction valve, following which the fluid passes over the latter and the stop 9 projecting into the bore 4 of the cylinder so as to reach finally the said bore 4.
- the fluid to be compressed passes through the channel 3 into the central body 1, passes over the plate-shaped member 10 forming the delivery valve and reaches the annular chamber 11 beyond said valve, said annular chamber 11 being subjected to the compressor pressure.
- the central body 1 By reason of the pressure prevailing in the annular chamber 11 and acting on the front surface 12 of the coaxial suction and delivery arrangement projecting into the annular chamber 11, the central body 1 is urged towards the front surface 6 of the inner ring 14 fitted inside the intermediate ring 13.
- the front surface 6 and the cooperating surface of the body 1 engaging said surface 6 are machined in a manner such that the pressure acting in said central body allows obtaining fluidtightness.
- an elastic member 16 as known per se.
- the area of the central body 1, registering with the central channel 3 subjected to the variable pressure prevailing inside the cylinder and extending between the incurved surface 7 closing the annular body 8 forming the suction valve and the fluidtight surface on the member 10 forming the delivery valve, is sujected together with the oblique channels to a constant suction pressure over a length which is substantially equal to its outer'periphery between the packing 17 and the bearing surface 6.
- the deformations of the ring 14 are reduced by reason of its high modulus of elasticity and the friction exerted on the bearing surface 6 also reduces the deformation of the adjacent area of the body 1.
- the strain to which the central body 1 is subjected and which is proportional to the modifications in shape are reduced in conformity with Hookes law.
- the fluidtig-ht seat surface 7 and the corresponding surface on the annular body 8 forming the suction valve are curvilinear.
- the axes of the sloping channels vcoincide preferably with radii of said incurved surfaces so as to reduce the risk of shearing.
- the pressure exerted on the bearing surface 6 and the higher modulus of elasticity of the ring 14 with reference to the modulus of the material forming the central body are such that the peaks of the stresses arising in registry with the incurved fluidtight surface 7 and ascribable to a shearing action, are reduced in a manner suflicient to cut out in practice any risk of a break.
- a coaxial suction and delivery valve arrangement adapted to equip high pressure compressors and pumps valve and the surface fluidtightly engaging the delivery valve, is equal to the length of the axial channel subjected to the pressure prevailing inside the cylinder.
