Compression pump

A compression pump comprising:

• a housing;
• an inlet valve;
• an exhaust valve;
• a piston;
• a bladder with a high-pressure side and a low-pressure side;
• a slide support supporting said bladder on said low-pressure side;
• a groove bearing supported by either of said housing or said piston;
• and
• a bridge having a bridge bearing supported by said housing if said groove bearing is supported by said piston, or said bridge bearing is supported by said piston if said groove bearing is supported by said housing,
• wherein, said groove bearing and said bridge, support said slide support,
• wherein:
• said housing comprises an entrance section, a center section and a crown section;
• said piston comprises an inlet section, a middle section and a head section;
• said housing entrance section comprises a cylinder;
• said inlet section is bound by said cylinder;
• said bladder has an inner perimeter and an outer perimeter, said outer perimeter being compressed between said center section and said crown section, and said inner perimeter being compressed between said head section and said middle section;
• a housing seat is formed between said entrance section and said center section, said housing seat receiving said bridge bearing if said groove bearing is supported by said housing, or said housing seat receiving said groove bearing if said bridge bearing is supported by said housing;
• and
• a piston seat is formed between said inlet section and said middle section, said piston seat receiving said groove bearing if said bridge bearing is received within said housing seat, or said piston seat receiving said bridge bearing if said groove bearing is received within said housing seat.

A compression pump comprising:

• a housing having a crown section with a crown section exterior face;
• a piston having a head section with a head section distal face and a valve seat;
• an inlet valve seated within said valve seat during a compression stroke, said inlet valve having an inlet valve distal end;
• an exhaust valve having an exhaust valve interior face;
• a bladder, said bladder, said crown section and head section defining a compression cavity, said bladder separating said compression cavity from a support void;
• and
• a support structure, said support structure being within said support void,
• at a position of top dead center, said piston is fully received within said housing wherein said head section distal face and said inlet valve distal end are planar with said exterior face of said crown section and the exhaust valve interior face.

A compression pump comprising:

• a housing;
• a piston, said piston being movable within said housing;
• an inlet valve;
• an exhaust valve;
• a bladder, said bladder, said housing and said piston defining a compression cavity;
• and
• a support structure supporting a low-pressure side of said bladder,
• wherein:
• said housing has an entrance section, a center section and a crown section;
• said piston has an inlet section, a middle section and a head section;
• said bladder has an inner perimeter and an outer perimeter, said inner perimeter being between said middle section and said head section, and said outer perimeter being between said center section and said crown section;
• said head section has a head section distal face and a valve seat;
• said inlet valve has a head that is received within said valve seat, said inlet valve further having an inlet valve distal end that is planar with said head section distal face when said inlet valve is in a closed position;
• said crown has a crown exterior face;
• and
• said inlet valve distal end and said head section distal face are planar with said crown exterior face and an interior face of said exhaust valve when said inlet valve is closed and said piston is at top dead center.
