Linear pump with vibration isolation

Abstract

A linear pump having an axially aligned cylinder and piston arrangement driven by an electromagnet motor. The cylinder, piston and motor are contained in and coupled to a housing by a vibration isolation system. The vibration isolation systems has resilient mounts connected between a motor mount and a base of the housing as well as resilient tubing extending between a valve head of the cylinder and intake and exhaust chambers of the pump.

1 . A linear pump comprising a cylinder and piston disposed along a piston axis and an electromagnet motor having a stator containing a wire coil driving an armature connected to the piston to reciprocate the piston within the cylinder along the piston axis, wherein the cylinder, piston and motor are contained in and coupled to a housing by a vibration isolation system including resilient mounts connected between a motor mount and a base of the housing and including a resilient tubing extending between a valve head of the cylinder and intake and exhaust chambers of the pump.  
   
   
       2 . The pump of  claim 1 , wherein the tubing is bellowed.  
   
   
       3 . The pump of  claim 1 , wherein the resilient mounts snap mount in place.  
   
   
       4 . The pump of  claim 3 , wherein the motor support plate has open-ended slots receiving the resilient mounts.  
   
   
       5 . The pump of  claim 1 , wherein the resilient mounts include an enlarged head disposed at a first side of the motor support plate and an enlarged foot disposed at a second side of the motor support plate opposite the first side.  
   
   
       6 . The pump of  claim 1 , wherein the housing base includes a base plate spaced from the motor mount having opening receiving the resilient mounts and openings for the intake and exhaust tubing.  
   
   
       7 . The pump of  claim 6 , wherein the base defines the intake and exhaust chambers.
