Abstract
The multi-way valve comprises two valve seats (12, 14) formed in the valve chamber whose seat surfaces are parallel. Two closing bodies (22, 24) cooperating with one of these valve seats (12, 14) respectively are attached to both ends of an elongated actuating member (20). To this actuating member (20) there is attached the one end of an elastic lamella (18) whose other end (18A) is braced at the valve chamber (10). The actuating member (20) may swivel rocker-like around a swivel axis (28) which is not fixed in space. Although no direct guide for the actuating member (20) is provided, a precise guiding largely free from tolerances is guaranteed so that the drive power required is low.
Claims31
A multi-way valve comprising:
- a valve body,
- a valve chamber disposed within said valve body,
- two valve seats formed in the valve chamber and having seat surfaces which are coplanar or parallel to each other,
- two closing bodies, each cooperating with a respective valve seat and being movably mounted in said valve chamber between a closing position in engagement with the respective valve seat and an opening position distant from said valve seat, the direction of movement from said closing position and said opening position being identical for both valve bodies;
- an elongated actuating member having opposite ends to which said closing bodies are respectively attached and being tiltably mounted in said valve chamber about an axis intermediate said opposite ends;
- and
- a drive engaging said actuating member, wherein at least one elastic lamella is connected to the actuating member via a flexible connection defining a friction-free and guide-free tilting axis therebetween,
- said lamella having a distal end remote from said actuating member and being firmly received by a portion of said valve body disposed within said valve chamber at said distal end,
- whereby said actuating member is tiltable with respect to said portion of said valve body about said friction-free and guide-free tilting axis to bring said closing bodies alternately into their closing and opening positions, said tilting axis moving in space when said actuating member is moved to bring the closing bodies into their opening and closing positions.
Multi-way valve according to claim 24, wherein the flat armature is a composite component made of magnet material and synthetic material, the synthetic material forming a coating surrounding the magnet material at least in part and being provided with elements for attaching the spring.
A multi-way valve comprising a valve body, a valve chamber disposed within the valve body, at least two valve seats formed in the valve with respect to each other, closing bodies associated with each of the valve seats respectively, a valve drive, as well as an actuating member disposed between the valve drive and the closing bodies, wherein the valve chamber is subdivided by a diaphragm into a first region wherein the valve chamber is situated and a second region wherein the valve drive and the actuating member are located and wherein the closing bodies are disposed at the diaphragm to be opposite the respective associated valve seat and connected to the diaphragm, each closing body connected to the actuating member via a coupling device and wherein the actuating member is formed of a spring lamella having free ends, the coupling device being connected respectively to said free ends, said actuating member being tiltably mounted in said valve chamber about a friction-free and guide-free axis via a flexible lamella section connected to said actuating member and firmly received by a portion of said valve body within said valve chamber whereby said actuating member is tiltable with respect to said portion of said valve body about said friction-free and guide-free tilting axis to bring said closing bodies alternately into their closing and opening positions.
4/2-way valve comprising a valve body and a valve chamber disposed within the valve body, four valve seats and associated closing bodies being actuated in pairs by a common valve drive, wherein said valve comprises two actuating members formed as a spring lamella, two closing bodies being respectively disposed at both ends of said actuating members, said actuating members comprising an elastic lamella section connected thereto, said lamella section having a distal end extending from said actuating members that is firmly received by a portion of the valve body within the valve chamber by means of which the actuating member is supported tiltably about a friction-free and guide-free axis to bring said closing bodies into their closing and opening positions, wherein the first of the two actuating members is disposed on the side of the valve drive and actuatable by the latter, while the second actuating member is connected to the first actuating member via a coupling device and actuatable by the latter.
