Thermostat housing for a thermostat of an engine cooling arrangement

Abstract

A housing for a thermostat includes a body, a cavity, at least one director member and at least one retainer member. The body defines an enclosure that receives coolant fluid. The enclosure is in fluid communication with a pump that pumps the coolant fluid to a sink for dissipating heat extracted by the coolant fluid. The cavity configured on body receives and holds thermostat that determines temperature of coolant fluid. The director member is configured on at least one internal wall of the enclosure and defines flow path of the coolant fluid so as to direct coolant fluid to thermostat and facilitate sufficient contact between coolant fluid and thermostat and the retainer member configured on the body is disposed around thermostat to prevent the coolant fluid from bypassing of the thermostat, thereby retaining coolant fluid in contact with thermostat to ensure precise sensing of temperature by the thermostat.

1 . A sensor housing comprising:
 a body defining an enclosure adapted to receive fluid;
 at least one receiver configured on said body and adapted to receive and hold at least one sensor that is adapted to determine at least one pre-determined property associated with fluid directed thereto as said fluid comes in contact with said at least one sensor; 
 at least one fluid flow director member configured on at least one internal wall of said enclosure and adapted to define flow path of said fluid through said enclosure so as to direct said fluid to said at least one sensor and facilitate sufficient contact between fluid and said at least one sensor to ensure precise sensing of said at least one pre-determined property associated with said fluid by said at least one sensor; and 
 at least one fluid retainer member configured on said body and disposed around said at least one sensor and adapted to prevent bypassing of said at least one sensor by the fluid and retain said fluid in contact with said at least one sensor for a pre-determined time to ensure precise sensing of said at least one pre-determined property associated with the fluid by said at least one sensor. 
   
     
     
         2 . (canceled) 
     
     
         3 . The sensor housing as claimed in  claim 1 , wherein said at least one sensor is selected from a group consisting of pH sensor, concentration sensor and temperature sensor. 
     
     
         4 . The sensor housing as claimed in  claim 1 , wherein said at least one fluid flow director member is a profiled by-pass gallery configured on said at least one internal wall of said enclosure. 
     
     
         5 . The sensor housing as claimed in  claim 1 , wherein said at least one fluid flow director member is a flap disposed on said at least one internal wall of said enclosure. 
     
     
         6 . (canceled) 
     
     
         7 . (canceled) 
     
     
         8 . A housing for a thermostat of a cooling arrangement for an engine of a vehicle, said housing comprising:
 a body defining an enclosure adapted to receive coolant fluid of the cooling arrangement after said coolant fluid has extracted heat from the engine, said enclosure is in fluid communication with a pump that pumps said coolant fluid to a sink of the cooling arrangement for dissipating heat extracted by said coolant fluid from the engine;   a receiver cavity configured on said body and adapted to receive and hold the thermostat that is adapted to determine temperature of coolant fluid directed thereto as said coolant fluid comes in contact with the thermostat;   at least one fluid flow director member configured on at least one internal wall of said enclosure and adapted to define flow path of said coolant fluid through said enclosure so as to direct coolant fluid to said thermostat and facilitate sufficient contact between said coolant fluid and said thermostat to ensure precise sensing of temperature of coolant fluid by the thermostat; and   at least one fluid retainer member configured on said body and disposed around said thermostat and adapted to prevent said coolant fluid from directly reaching suction of said pump by bypassing of said thermostat, thereby retaining said coolant fluid in contact with said thermostat for a pre-determined time to ensure precise sensing of temperature of coolant fluid by said thermostat.   
     
     
         9 . The sensor housing as claimed in  claim 8 , wherein said at least one fluid retainer member is a flow balancer rib that is configured on a valve rest face of thermostat and disposed around said thermostat. 
     
     
         10 . The sensor housing as claimed in  claim 9 , wherein said flow balancer rib is adapted to balance coolant flow to said pump and said thermostat.
