Definitions

  • the present invention relates to a novel pressure control unit for piston compressors, which was never described in prior art up to the present
  • the main object of the present invention is to combine all essential devices used in conjunction with a piston compressor into one equipment
  • the piston compressor is part of a group of positive displacement compressors (volumetric) and essentially uses a connecting rod and piston assembly, in order to convert the rotary motion of a translational axis of a piston or plunger
  • the piston performs a forth stroke and another back stroke in the direction of the cylinder head, creating a cycle of operation
  • This type of compressor has its operation closely related to the valves that control the air input, air compression and air expansion cycles
  • air compressors including piston compressors
  • said instruments and components comprise
  • Pressure gauges which are used to indicate the existing air pressures Generally, these pressure gauges indicate the pressure within the compressor reservoirs and the pressure of the air outlet,
  • the first disadvantage refers to the existence of different points of connection, which results in higher probability of air leakage between said above-mentioned components and instruments
  • the second disadvantage refers to the need of assembly and eventual welding of all above-mentioned components and instruments, which requires time and qualified labor
  • the present invention was developed in order to overcome these and other drawbacks of the prior art, by providing a novel pressure control unit for air compressors, which was never described in prior art up to the present
  • the pressure control unit comprises all basic instruments and components combined into a single robust and practical housing
  • the pressure control unit has a major model and a constructive variant, wherein said major model is essentially digital and said constructive variant is essentially analog
  • Figure 1 illustrates a front upper perspective view of the pressure control unit, according to the present invention
  • Figure 2 illustrates a side lower perspective view of the pressure control unit, according to the present invention
  • Figure 3 illustrates a front upper perspective view of a constructive variant of the pressure control unit depicted in Figures 1 and 2, according to the present invention
  • the pressure control unit which is indicated with the reference numeral (1), comprises an essentially quadrangular body formed by the unification of an upper portion (2) and a lower portion (3)

  • Said selector switch (3.6) has an open/closed position.
  • Said lower portion (3) also has a safety valve (3.9) and a pressure relief valve (3.10) arranged in one of its side walls. It is also noted an air outlet hole (3.11) arranged in the side wall opposite to the above-mentioned wall.
  • the pressure control unit (1 ), according to the present invention was designed to replace all of the basic instruments and devices used in conjunction with compressors. Consequently, the pressure control unit (1 ), according to the present invention, comprises a single air input (3.8), wherein said air input (3.8) is connected to the air output of the compressor (not shown). The compressed air from the compressor "feeds" then the pressure control unit (1 ).
  • the pressure of this compressed air is adjusted by a handle (3.4) of a pressure-regulating valve.
  • the air obtained in the air output hole (3.11) is sized as needed by said pressure-regulating valve.
  • Said digital display (2.3) was designed to indicate the internal pressure of the compressor (the same pressure in the air input (3.8)), the working pressure (the pressure of the air output hole (3.11)), and the set point (the amount of pressure required to turn-on and turn-off the engine and the compressor).

  • said constructive variant comprises only one analog dual pressure indicator (4.1) on the face of its upper portion.
  • Said analog dual pressure indicator (4.1) is provided with two scales and two pointers (a pointer for each scale).
  • a scale and its respective pointer indicate the pressure of the compressor (and therefore, the inlet pressure), and the other said scale and its respective pointer indicate the output pressure.
  • the constructive variant (4) does not have switching buttons and light-emitting signaling units, and pressure values for switching on/off the motor are pre-adjusted during the production process.
  • control unit of pressure (1) offers many advantages For manufacturers of compressors, the main advantages can be summarized as follows
  • the pressure control unit (1 ) exhibits technical merit, absolute novelty, inventive activity and industrial applicability, therefore fully deserving the privilege of the invention now being claimed

Abstract

L'invention concerne un nouveau régulateur de pression (1) de compresseur d'air jamais décrit jusqu'alors. Ledit régulateur (1) comporte les instruments et composants de base c,-à-d.: une soupape régulatrice de pression (3.4), une soupape de sûreté (3.9), une soupape de décharge (3.10), un bouton d'arrêt d'urgence (2.6), et un commutateur de sélection (3.6), le tout intégré dans un carter robuste et pratique (2,3) présentant une entrée (3.8) et une sortie (3.11). Selon l'invention, le régulateur de pression (1) présente un modèle principal et une variante de construction, ledit modèle principal étant essentiellement numérique (2.3, 2.4, 2.5) et la variante de construction essentiellement analogique (4.1). Selon l'invention, les principaux avantages de l'utilisation dudit régulateur de pression(1) découlent des caractéristiques suivantes: facilité d'installation, interface simple et agréable et longue durée de vie des composants et instruments, lesquels sont protégés par un carter robuste.
