20100229717 | Linear Compressor With Sintered Bearing Bush - A linear compressor includes a piston housing having a plurality of gas permeable openings therein and a compressor piston configured for reciprocatory motion therein along an axis, the compressor piston being supported in the piston housing by gas flowing through the openings and wherein the housing wall is porous. | 09-16-2010 |
20100326271 | RECIPROCATING PUMP AND METHOD FOR MAKING A SYSTEM WITH ENHANCED DYNAMIC SEAL RELIABILITY - A pressure pump may include a reciprocating assembly including a dynamic seal configured to be in sliding contact with a surface. The surface may be implanted with positive ions such as hydrogen ions/protons to provided reduced wear and/or greater service life of the dynamic seal. According to embodiments, a pump may include an ultra-high molecular weight polyethylene dynamic seal may substantially fixed relative to a cylinder wall, and a proton impregnated reciprocating plunger may pump high pressure water or a water based fluid in a system. The pump may exhibit increased dynamic seal life. | 12-30-2010 |
20130008306 | REINFORCED THERMOPLASTIC ACTUATOR WITH WEAR RESISTANT PLASTIC LINER - A fluid actuator includes a housing having a fluid chamber providing a first friction surface. An actuating member is arranged in the fluid chamber and has a second friction surface slideably engaging the first friction surface. The actuating member is configured to slide within the chamber between first and second positions. An insert is constructed from a first thermoplastic material and provides one of the first and second friction surfaces. A body structurally supports the insert and provides one of the housing or actuating member. The body is constructed from a second thermoplastic material molded about the insert and including short reinforcing fibers. | 01-10-2013 |
20140102292 | PRIMARY PLASTIC PISTON WITH FUNCTIONAL INSERT FOR A PENETRATION-TYPE MASTER CYLINDER AND A MASTER CYLINDER EQUIPPED WITH SUCH A PISTON - A primary piston is described of molded plastic and equipped with a functional metallic insert and at least one groove. The primary piston is installed in a master cylinder comprising at least the primary piston and a secondary piston, these being mounted in the bore hole of a master cylinder. These pistons can create pressure in a primary pressure chamber and a secondary pressure chamber, respectively, due to the action of a push rod on the primary piston. | 04-17-2014 |
20150059570 | Cylinder Seat of an Air Compressor of a Tire Repair Machine - A cylinder seat of an air compressor of a tire repair machine, comprising a seat board, a cylinder, and a motor seat is provided; the seat board includes a first surface and a second surface that is opposite to the first surface; the cylinder is integrated with the seat board and is disposed on the first surface of the seat board; an opening configured to accommodate a plunger is defined in one end of the cylinder, and a one-way valve device is mounted on another opposite end of the cylinder; and the motor seat is integrated with the seat board and is disposed on the second surface of the seat board. Thus, the overall structure of the cylinder seat is simple, and the manufacturing cost can be decreased. | 03-05-2015 |
