GAS CARTRIDGE AND ASSEMBLY COMPRISING A GAS APPLIANCE CONNECTION DEVICE AND A GAS CARTRIDGE

The present application relates to a device for connecting a gas appliance and an assembly comprising a device for connecting a gas appliance and a gas appliance.

Patent document FR2876776A1 discloses a device for connecting a gas appliance of the type comprising a valve pusher. When the gas appliance connector is mechanically connected to and locked to the gas cartridge, the valve pusher opens the valve of the gas cartridge. The gas appliance connector is then fluidly connected to the gas cartridge.

Although satisfactory, this type of gas appliance connection device can still be improved. In particular, it may facilitate mechanical connection, mechanical disconnection, locking, unlocking, fluid connection, fluid disconnection, or even use thereof. More specifically, it is possible to prevent gas from remaining in the gas appliance connecting device during mechanical disconnection. It is possible to improve the gas flow control of the gas appliance connecting device during use. The present application aims to achieve all or part of these objects.

Gas cartridges are also known that include a valve and a joint configured to move between a closed position and a fully open position. When the valve is in the closed position, the gas flow has a value of zero. When the valve is in the maximum open position, the gas flow has a maximum value (maximum flow).

Initially, the gas appliance connection device and the gas cartridge can be mechanically and fluidly disconnected. A user may mechanically and fluidly connect the gas appliance connector to the gas cartridge by bringing the gas appliance connector over the gas cartridge. The valve is momentarily moved between the closed position and the fully open position by the valve pusher. Therefore, this type of gas cartridge is referred to as "on/off".

Although satisfactory, this type of gas cartridge can still be improved. In particular, the gas flow rate control of the gas cartridge can be made more gradual. The present application aims to achieve all or part of these objects.

One aspect of the present application is a gas cartridge, comprising a valve comprising a poppet configured to move between a closed position and a fully open position by passing through a joint and a plurality of intermediate open positions, the poppet including the poppet in the closed position. a first contact portion arranged to contact the joint when in; a second contact portion arranged to contact the valve pusher of the gas appliance connecting device when the poppet is moved between the closed position and the maximum open position through the plurality of intermediate open positions; and a connection portion connecting the first contact portion and the second contact portion, the connection portion configured to increase a gas passage cross-sectional area between the joint and the connection portion when the poppet is moved between the closed position and the maximum open position through the plurality of intermediate open positions. which relates to a gas cartridge.

Initially, the gas appliance connection device and the gas cartridge may be mechanically and fluidly disconnected.

A user may mechanically connect the gas appliance connector to the gas cartridge by attaching the gas appliance connector to the gas cartridge or vice versa by attaching the gas cartridge below the gas appliance connector.

A user may fluidly connect the gas appliance connection device to the gas cartridge. The valve pusher may move from a retracted position to a maximum forward position via a plurality of intermediate forward positions. The poppet can thus be moved between a closed position and a fully open position by passing through a plurality of intermediate open positions.

When the poppet is in the closed position, the gas flow rate has a value of zero.

When the poppet is in the open position, the gas flow has a maximum value (maximum flow).

When the poppet is in the mid-open position, the gas flow rate has an intermediate value.

The poppet joint is formed such that the gas passage cross-sectional area between the joint and the joint gradually increases (either linearly or non-linearly) as the poppet moves between the closed position and the maximum open position through a plurality of intermediate open positions.

The gas passage cross-sectional area between the joint and the poppet connection may be defined as the smallest cross-sectional area between the joint and the poppet connection.

Thus, the connection of the poppet is shaped so that the gas flow rate can be adjusted gradually. The gas flow rate can have multiple intermediate values in addition to zero and maximum values (no longer just zero and maximum values as in certain so-called "ON/OFF" type gas cartridges). .

The stroke of the poppet between the closed position and the maximum open position passing through the plurality of intermediate open positions may be 5 mm or less, 4 mm or less, 3 mm or less, or 1 mm or less.

The joint may have a 'T'-shaped longitudinal cross-section.

The joint may comprise a straight cylindrical body receiving the head and therein the connection of the poppet X, and the connection of the poppet may be tapered.

The gas passage cross-sectional area between the joint and the poppet connection may be defined as the smallest cross-sectional area between the body of the joint and the poppet connection.

Conversely, the joint may comprise a frustum and the junction of the poppet may be straight cylindrical.

The joint between the body of the joint and the poppet forms an angle of 3 degrees to 40 degrees, 3 degrees to 30 degrees, 3 degrees to 20 degrees, or 3 degrees to 10 degrees.

The connecting portion of the poppet may be straight cylindrical and may include a plurality of longitudinal openings.

The plurality of longitudinal openings may not be open radially.

In other words, the plurality of longitudinal openings are closed in the radial direction.

The plurality of longitudinal openings may be open in the longitudinal direction.

The plurality of longitudinal openings may each have a different length.

The plurality of longitudinal openings may include 4, 6, 8 or 10 longitudinal openings.

The plurality of longitudinal openings may be distributed equiangularly (at regular angles) around the joint of the poppet.

The plurality of longitudinal openings may include a plurality of grooves.

The second contact may include a spider.

The second contact portion may be formed male or female.

When the second contact is formed male, the second contact may have a protrusion intended to cooperate with the valve pusher of the gas appliance connecting device.

When the second contact is formed female, the second contact may have a recess intended to cooperate with the valve pusher of the gas appliance connecting device.

The gas cartridge may contain gas (the gas cartridge may be full or partially full), or may be out of gas (the gas cartridge may be empty). The gas may be petroleum gas. The gas may comprise a mixture of propane and/or butane.

One aspect of the present application, as an assembly, the above-described gas cartridge; and a gas appliance connection device comprising a valve pusher and a first control member, wherein the valve pusher is configured to be moved between a retracted position and a maximum forward position by passing the plurality of intermediate forward positions, and wherein the first control member comprises: The first control member passes through the plurality of intermediate open positions for moving the valve pusher to the plurality of intermediate forward positions, whereby the closed position for moving the valve pusher to the retracted position and the first control member move the valve pusher to the maximum forward position. and a gas appliance connection device comprising a first control member configured to move between a moving maximum open position.

1 to 15 show a first gas appliance (not shown) connection device 2 . For example, the gas appliance may be a simple burner stove or lamp.

The connecting device 2 comprises a body 4 and an injector 6 . The injectors 6 are configured to be in turn mounted to and removed from the body 4 . For example, the injector 6 is configured to be screwed to and unscrewed from the body 4 in turn. The injectors 6 are arranged in turn to be fluidly connected to and fluidly disconnected from the gas device. Here the injector 6 opens upwards.

In a configuration not shown, the injectors 6 are configured to be screwed to and unscrewed from the valve pusher 8 in turn. In this configuration, the gas appliance is configured to be screwed to and unscrewed from the valve pusher 8 in turn.

The gas appliance is configured to be in turn mounted on the connecting device 2 and screwed off from the connecting device 2 . Here, the gas appliance is configured to be screwed to and unscrewed from the body 4 in turn.

The connecting device 2 comprises a valve pusher 8 (or the valve pusher shown in FIGS. 3 , 6 , 9 , 10 and 15 ). The valve pushers 8 are configured to be alternately mounted to and disassembled from the body 4 . The valve pusher 8 is in a retracted or elevated position ( FIGS. 3 , 6 and FIG. 3 , 6 and FIG. 15 ) and the valve pusher 8 is configured to move between a forward or low position (shown in FIG. 9 ) that is advanced to allow opening of the valve 10a of the gas cartridge 10 . The valve pusher 8 is configured to slide inside the body 4 . The valve pusher 8 is tubular. The valve pusher 8 comprises a first annular part 8a and a second annular part 8b, the functions of which will become apparent later. In the retracted position, the valve pusher 8 is arranged to be fluidly disconnected from the gas cartridge 10 . In the forward position, the valve pusher 8 is arranged in fluid connection to the gas cartridge 10 .

The gas cartridge 10 (shown in FIG. 15) includes a valve. The valve includes a valve 10a, a seat 10b (or a seal), and an elastic return member (not shown) for returning the valve 10a toward the seat 10b. The valve 10a has a bottom wall 10c. The valve 10a has a bottom wall to help maintain a distance between the valve pusher 8 and the bottom wall 10c of the valve 10a when the valve pusher 8 is in the forward position (shown in FIG. 9 ). and a crosspiece 10d arranged in 10c. The gas cartridge 10 also includes a collar 10f.

When the valve pusher 8 is in the retracted position (shown in Figs. 3, 6 and 15), the resilient return member pushes the valve 10a toward the seat 10b. The valve 10a is in contact with the seat 10b, and the gas contained in the gas cartridge 10 cannot flow between the valve 10a and the seat 10b, and thus the valve 10a from the outside of the valve 10a. ) cannot flow inward.

When the valve pusher 8 is in the forward position (shown in FIG. 9 ), the valve pusher 8 pushes the valve 10a in the opposite direction to the seat 10b . The valve 10a is remote from the seat 10b, and the gas contained in the gas cartridge 10 can flow between the valve 10a and the seat 10b. The valve pusher 8 is spaced from the bottom wall 10c of the valve 10a in contact with the spider 10d. The valve pusher 8 is also away from the sidewall 10e of the valve 10a. Accordingly, when the valve pusher 8 is in the forward position, the gas contained in the gas cartridge 10 can flow into the valve pusher 8 inside the valve 10a.

The connecting device 2 comprises a control element 12 . The control members 12 are configured to be alternately mounted to and disassembled from the body 4 . The control member 12 is configured to move between a closed position (shown in FIGS. 1-6 and 12-15 ) and an open position (shown in FIGS. 7-9 ). In the closed position, the control member 12 moves the valve pusher 8 to the retracted position (shown in FIGS. 3 , 6 and 15 ). In the open position, the control member 12 moves the valve pusher 8 to the forward position (shown in FIG. 9 ).

The valve pusher 8 and the control member 12 allow the control member 12 to be positioned between a closed position (shown in FIGS. 1 to 6 and 12 to 15 ) and a first intermediate position (shown in FIG. 11 ). The valve pusher 8 is configured to remain in the retracted position when moving. The connecting device 2 thus makes it possible to keep up with industrial tolerances, and the control element 12 (shown in FIGS. 1 to 6 and 12 to 15 ) and a first intermediate position (shown in FIG. 11 ) ) to ensure that no fluid connection is made between the valve pusher ( 8 ) and the gas cartridge ( 10 ) when moving between them.

The valve pusher 8 and the control member 12 are connected to the valve pusher 8 when the control member 12 moves at a fixed pitch between a first intermediate position (shown in FIG. 11 ) and a second intermediate position (not shown). is configured to move at a variable pitch between the retracted position (shown in FIGS. 3 , 6 and 15 ) and a third intermediate position (not shown).

The valve pusher 8 and the control member 12 are connected to the valve pusher 8 as the control member 12 moves at a fixed pitch between a second intermediate position (not shown) and an open position (shown in FIGS. 7-9 ). ) is configured to move with a fixed pitch or a variable pitch between a third intermediate position (not shown) and a forward position (shown in Figure 9).

The valve pusher 8 is fluidly connected to the gas cartridge 10 when the control member moves between a first intermediate position (shown in FIG. 11 ) and a second intermediate position (not shown). The degree of opening of the valve 10a of the gas cartridge 10 increases (eg, non-linearly or sinusoidally). The flow rate of the gas circulating through the valve 10a of the gas cartridge 10 increases (eg, non-linearly or sinusoidally).

The valve pusher 8 is still fluidly connected to the gas cartridge when the control member 12 is moved between the second intermediate position (not shown) and the open position (shown in FIGS. 7-9 ). The opening of the valve 10a of the gas cartridge 10 is increased (eg linearly or sinusoidally) until a maximum opening is reached. The flow rate of gas circulating through valve 10a of gas cartridge 10 increases (eg linearly or sinusoidally) until a maximum flow rate is reached. Accordingly, adjustment of the gas flow rate between the gas cartridge 10 and the gas appliance can be facilitated.

Here, the control member 12 controls the camshaft 12a, the cam 12b mounted on the first end of the camshaft 12a, and the adjustment knob 12c (or flywheel) mounted on the second end of the camshaft 12a. include The cam 12b is arranged to rest on the valve pusher 8 . Here, the cam 12b is arranged to be received between the first annular part 8a and the second annular part 8b of the valve pusher 8 . The cam 12b forms a second annular portion ( 8b) is arranged to be supported. The cam 12b forms a first annular portion ( 8a) is arranged to be supported. The pitch of the valve pusher 8 is defined by the shape of the valve pusher 8 and/or the cam 12b. Here, the adjustment knob 12c is arranged to be rotated between at least 0 degrees and 180 degrees. The first intermediate position (shown in FIG. 11 ) is between 20 and 100 degrees. A second intermediate position (not shown) is located between 105 degrees and 180 degrees. It should be understood that other ranges of values are possible.

The control member 12 is mounted to the body 4 by way of a grip screw 13 received, for example, in a bore of the body 4 and a semi-circular groove of the cam 12b.

The stroke of the control member 12 between the first closed position and the maximum open position is long (typically 180 degrees). On the other hand, the stroke of the valve pusher 8 between the retracted position and the maximum forward position is very short (typically about 1 mm). In addition, it may be difficult to convert a long stroke of the control member 12 into a short stroke of the valve pusher 8 , the position of the valve pusher 8 , the opening degree of the valve 10a and the flow rate of gas exiting the gas cartridge may be difficult to fine-tune.

A solution to this problem may be to finely adjust the shape of the cam 12b. However, the required industry tolerances are too low (typically on the order of hundredths of a millimeter), and the associated costs will obviously be too high for the purpose pursued.

An alternative solution to this problem is described below with reference to FIGS. 20-29 , which proposes to modify the gas cartridge 10 rather than focus on the shape of the cam 12b.

The connecting device 2 has a locking member 14 ( FIGS. 3 , 6 and 15 ) configured to move between an unlocked position (shown in FIG. 3 ) and a locked position (shown in FIGS. 6 , 9 and 15 ). 9 and 10). When the locking member 14 is in the locked position (shown in FIGS. 6, 9 and 15 ), the locking member 14 locks the connecting device 2 to the gas cartridge 10 . When the locking member 14 is in the unlocked position (shown in FIG. 3 ), the locking member unlocks the connecting device 2 against the gas cartridge. The locking member 14 is mounted to the body 4 by means of a screw 15 which is received, for example, through a bore in the body 4 and a hole in the locking member 14 .

Here, the locking member 14 comprises a ring comprising a lug. The legs extend in the longitudinal direction (ie along an axis parallel to the axis of the valve pusher 8 ). The legs are elastically deformable in the radial direction (ie elastically deformable or movable along a plane perpendicular to the axis of the valve pusher 8 ).

The connecting device 2 comprises a control member 16 configured to be moved between an unlocked position (shown in FIGS. 1 to 3 ) and a locked position (shown in FIGS. 4 to 9 , 14 and 15 ). do. When the control member 16 is in the locked position (shown in FIGS. 4 to 9 , 14 and 15 ), the control member 16 moves the locking member 14 to the locked position ( FIGS. 4 to 9 , FIG. 15 ). 14 and 15). When the control member 16 is in the unlocked position (shown in FIGS. 1-3), the control member 16 moves the locking member 14 to the unlocked position (see FIG. 3).

Here, the control member 16 comprises a ring comprising a projection. The projection extends radially inwardly (ie along a plane perpendicular to the axis of the valve pusher 8 ).

The control member 16 is configured such that the projections are supported against the lugs and the lugs are deformed or moved radially inward when the control member 16 is in the locked position (shown in FIGS. 4-9 , 14 and 15). It is rotatably mounted to the locking member 14 to engage the flange 10f of the gas cartridge 10 . When the control member 16 is in the unlocked position (shown in FIGS. 1 to 3 ), the protrusion releases the lug, and the lug further engages the collar 10f of the gas cartridge 10 radially inward. does not transform or move to

The control member 12 and the control member 16 allow the control member 16 to move between the closed position and the open position when the control member 16 is in the unlocked position (shown in FIGS. 1 to 3 ). (12) is configured to prevent movement.

Conversely, the control member 12 and the control member 16 allow the control member 12 to move between the locked position and the unlocked position when the control member 12 is in the open position (shown in FIGS. 7 to 9 ). configured to prevent displacement of the control member 16 .

Here, the control member 12 and the control member 16 ensure that the control member 16 is perpendicular to the control device 12 when the control member 16 is in the unlocked position (shown in FIGS. 1 to 3 ). is configured to be

For example, the control member 12 and the control member 16 may have a flat portion of the control member 12 when the control member 16 is in the unlocked position (shown in FIGS. 1-3). 16) is configured to face the flat part.

The control member 12 and the control member 16 have the control member 16 in the closed position and the open position when the control member 16 is in the locked position (shown in FIGS. 4 to 9 , 14 and 15 ). configured to allow movement of the control member 12 therebetween.

Conversely, the control member 12 and the control member 16 allow the control member 12 to move into the locked position when the control member 12 is in the closed position (shown in FIGS. 1-6 and 12-15). configured to allow movement of the control member 16 between the unlocked positions.

Here, the control member 12 and the control member 16 allow the control member 16 to move the control member 12 when the second control member is in the locked position (shown in FIGS. 4 to 9 , 14 and 15 ). ) so that it is not directly above it.

For example, the control member 12 and the control member 16 may have a flat surface of the control member 12 when the control member 16 is in the locked position (shown in FIGS. 4-9 , 14 and 15 ). The portion is configured such that it does not face the flat portion of the control member 16 .

It is understood that other mechanisms are possible. Instead of a mechanism using flat parts, it is possible to use a mechanism using, for example, pins and orifices.

The coupling device 2 comprises a coupling device 2 and a centering member 18 arranged to center the gas cartridge 10 . Here, the centering member 18 and the locking member are integrally formed. The centering member 18 includes a ring arranged to be received within the collar 10f of the gas cartridge 10 .

The connecting device 2 comprises a plurality of magnets 20 . The plurality of magnets 20 are arranged to extend over the flange 10f of the gas cartridge 10 when the ring is received inside the flange 10f of the gas cartridge 10 . Here, the plurality of magnets are arranged in a circle. The plurality of magnets are arranged along the isometric lines. The isolines form an angle of 120 degrees. The plurality of magnets are arranged in groups of magnets. Each magnet group has 2 or 3 magnets. Each magnet extends longitudinally (ie, along an axis parallel to the axis of the valve pusher 8 ). Each magnet is received in an orifice of a centering member 18 provided for this purpose.

The use of the connecting device 2 will now be described.

The user mounts the gas appliance to the connecting device 2 .

The user attaches the gas appliance and the connecting device 2 to the gas cartridge 10 . The connecting device 2 is mechanically connected to the gas cartridge 10 (shown in FIGS. 1 to 3 ). The centering member 18 is received in the collar 10f of the gas cartridge 10 . A plurality of magnets 20 hold the connecting device 2 against the gas cartridge 10 .

The user locks the connection device 2 against the gas cartridge 10 . The user moves the control member 16 from the unlocked position to the locked position (shown in FIGS. 4-6 ).

A user fluidly connects the connection device 2 to the gas cartridge 10 . The user moves the control member 12 from the closed position to the open position (shown in FIGS. 7-9 ).

The connection device 2 is advantageous in that the stages of mechanical connection, locking and fluid connection are distinct. The locking step cannot be performed until the mechanical connection step is complete. The fluid connection step cannot be performed until the locking step has been performed. The steps of mechanical connection, locking and fluid connection can thus be performed more safely.

After use, the user disconnects the connection device 2 from the gas cartridge 10 in fluid connection. The user moves the control member 12 from the open position to the closed position (shown in FIGS. 4-6 ).

The user unlocks the gas cartridge 10 of the connection device 2 . The user moves the control member 16 from the locked position to the unlocked position (shown in FIGS. 1 to 3 ).

The user disconnects the mechanical connection of the connecting device 2 from the gas cartridge 10 . The centering member 18 is no longer received in the collar 10f of the gas cartridge 10 . The plurality of magnets 20 no longer hold the connecting device 2 against the gas cartridge 10 .

The user disassembles the gas appliance from the connecting device 2 .

The connection device 2 is advantageous in that the stages of fluid disconnection, unlocking and mechanical disconnection are distinct. The unlocking step cannot be performed until the fluid disconnecting step is performed. The mechanical disconnection step cannot be performed until the unlocking step has been performed. The steps of fluid disconnection, unlocking and mechanical disconnection can thus be performed more safely.

Since the fluid disconnection phase is separate from the unlocking phase and the mechanical disconnecting phase, no gas leaks from the connection device 2 or gas cartridge 10 during the unlocking phase and the mechanical disconnection phase and "pschitt" "It doesn't work.

On the other hand, the connecting device 202 and the gas appliance are no longer attached to the gas cartridge 10 . The connecting device 202 and the gas appliance are disposed on the ground, and the gas cartridge is attached below the connecting device 202 and the gas appliance. Control member 16 is replaced by control member 116 , which includes a handle that facilitates operation of control member 116 without access underneath the gas appliance. For example, the gas appliance may be a grill.

20 is a cross-sectional view of the gas cartridge 310 . The gas cartridge 310 may be filled with gas (the gas cartridge may be full or partially full) or may be empty of gas (the gas cartridge may be empty). The gas may be petroleum gas. The gas may comprise a mixture of propane and/or butane.

The gas cartridge 310 includes a flange 312 and a valve 314 arranged inside the flange 312 . Valve 314 moves cage 316 , first poppet 318 (also shown in FIGS. 21 and 22 ), seat 320 (or joint), and first poppet 318 toward seat 320 . The turning includes a resilient return member 322 .

The first poppet 318 is configured to move between a closed position and a fully open position by passing through a plurality of intermediate open positions.

The first poppet 318 includes a first contact portion 318a arranged to contact the joint 320 when the poppet 318 is in the closed position. The first contact 318a includes a longitudinal gas passage. The gas passage has a groove. The longitudinal gas passage is longitudinally open at an upper end and a lower end. The longitudinal gas passages do not exit radially. Here, the longitudinal gas passages comprise four longitudinal gas passages, but other numbers of the longitudinal gas passages are conceivable.

The first poppet 318 is a valve pusher 8 of the gas appliance connecting device 2 , 102 or 202 when the first poppet 318 is moved between a closed position and a fully open position through a plurality of intermediate open positions. and a second contact portion 318b arranged to contact the The second contact portion 318b includes a spider. The second contact portion 318b is formed in a male shape. The second contact 318b has a projection intended to cooperate with the valve pusher 8 of the gas appliance connecting device 2 , 102 or 202 .
