US 5,600,953 A · Compressed air control apparatus

Abstract

The invention is directed to a compressed air control apparatus for supplying compressed air to a pneumatic actuator, which includes a compressor having a head member with a pressure chamber defined therein for generating compressed air, an intake valve for introducing air into the pressure chamber, and a discharge valve for discharging the compressed air. A dryer is disposed in a dry housing to dry the compressed air discharged from the compressor. A supply solenoid valve is disposed in a supply valve housing to control the compressed air supplied to the pneumatic actuator. An exhaust solenoid valve is disposed in an exhaust valve housing to control the compressed air discharged from the pneumatic actuator. The head member, dry housing, supply valve housing and exhaust valve housing are integrally formed by synthetic resin to provide an integral housing.

A compressed air control apparatus for supplying compressed air to a pneumatic actuator, comprising:

a compressor that includes a cylinder with an open end, a head member secured to the open end of said cylinder, a piston slidably positioned in said cylinder to form a pressure chamber within said cylinder between the head member and the piston for generating compressed air, an intake valve for introducing air into said pressure chamber, and a discharge valve for discharging compressed air from the pressure chamber;
dry means disposed in a dry housing for drying the compressed air discharged from said compressor;
supply valve means disposed in a supply valve housing for controlling the compressed air to be supplied to said pneumatic actuator;
exhaust valve means disposed in an exhaust valve housing for controlling the compressed air to be discharged from said pneumatic actuator,
said drying housing, supply valve housing and exhaust valve housing being disposed in the vicinity of the head member, said head member, dry housing, supply valve housing and exhaust valve housing being integrally formed of synthetic resin to define a single piece integral housing.
