Pressure valve for a compressor

Abstract

A pressure valve for a compressor of the hermetically encapsulated type. The valve includes a valve plate with a valve seat and upstanding pins on which at least one catch plate is placed to limit the stroke of a closing member formed by a valve leaf spring. The valve seat is disposed in an elongated depression of the valve plate and the pins are formed on an insert spring into the recess.

I claim: 
     
       1. A pressure valve for a compressor, comprising, a valve plate, a valve cover, a valve seal disposed between said valve plate and said valve cover, means connecting said valve cover to said valve plate, said valve plate having an elongated recess in the surface thereof in which is disposed an aperture and a surrounding valve seat, an elongated resilient insert having upstanding pins, said insert being sprung into said elongated recess, an elongated resilient leaf spring having a recess at one end thereof in which one of said pins is disposed, and an elongated catch plate for limiting the stroke of said leaf spring. 
     
     
       2. A pressure valve according to claim 1 characterized in that said upstanding pins are at the ends of said insert, said insert having an elongated cut-out section, said leaf spring being disposed in said cut-out section. 
     
     
       3. A pressure valve according to claim 1 characterized in that the end sections of said insert are bowed to facilitate mounting said insert in said recess. 
     
     
       4. A pressure valve according to claim 1 characterized in that said pins are made in one piece with said insert. 
     
     
       5. A pressure valve according to claim 3 characterized by said insert end sections have detent projections, said leaf spring having recesses in which said projections are disposed. 
     
     
       6. A pressure valve according to claim 5 characterized in that an auxiliary valve leaf spring covers said leaf spring, said auxiliary leaf spring also having recesses in which said projections are disposed. 
     
     
       7. A pressure valve according to claim 6 characterized in that said leaf spring and said auxiliary leaf spring have end located recesses in which said pins are disposed. 
     
     
       8. A pressure valve according to claim 6 wherein the thickness of said insert is somewhat greater than the thickness of at least one of said leaf springs. 
     
     
       9. A pressure valve according to claim 5 characterized in that said catch plate has recesses at the ends thereof in which said upstanding pins are disposed, and a bridge spring clamped in abutting engagement with said catch plate via said upstanding pins. .Iadd. 
     
     
       10.  A pressure valve for a compressor, comprising, a valve plate, a valve cover, a valve seal disposed between said valve plate and said valve cover, means connecting said valve cover to said valve plate, said valve plate having an elongated recess in the surface thereof in which is disposed an aperture and a surrounding valve seat, an elongated resilient insert having an elongated cut-out section with at least one inwardly extending detent projection at one end thereon, said insert being sprung into said elongated recess, an elongated resilient leaf spring disposed in said cut-out section and having a notch recess at one end thereof in which said detent projection is disposed, and an elongated catch plate for limiting the stroke of said leaf spring. .Iaddend. .Iadd.11. A pressure valve according to claim 10 characterized in that the end sections of said insert are bowed to facilitate mounting said insert in said elongated recess. .Iaddend. .Iadd.12. A pressure valve according to claim 10 characterized in that said detent projection is made in one piece with said insert. .Iaddend. .Iadd.13. A pressure valve according to claim 11 characterized by said insert one end section having additional inwardly extending projections, and said leaf spring having additional notch recesses in which said additional inwardly extending projections are disposed. .Iaddend. .Iadd.14. A pressure valve according to claim 13 characterized by a second inwardly extending detent projection at the opposite end of said insert, an auxiliary valve leaf spring covering said leaf spring, said auxiliary leaf spring also having notch recesses in which said inwardly extending detent projections of said elongated 
     
     
        resilient insert are disposed. .Iaddend. .Iadd.15.  A pressure valve according to claim 14 wherein the thickness of said insert is somewhat greater than the thickness of at least one of said leaf springs. .Iaddend. .Iadd.16. A pressure valve according to claim 13 characterized in that said catch plate is disposed in abutting engagement with said insert, a second inwardly extending detent projection at the other end of said cut-out section, and a bridge spring is clamped in abutting engagement with said catch plate via said inwardly extending detent projections. .Iaddend.
