Rotary piston cylinder

Abstract

The invention discloses a rotary piston cylinder, which is a mechanism capable of positively / reversely converting fluid pressure energy and mechanical energy in a one-way continuous circular motion mode. The rotary piston cylinder mainly comprises a cylinder body (1), a rotor (2), a clapboard (3), a working medium inlet (4), a working medium outlet (5), a rotary piston (6) and a crankshaft connecting rod mechanism (7). The working principle of the rotary piston cylinder is the same as that of a vane type oscillating cylinder. The rotary piston cylinder is characterized in that: the working rotary piston (6) displaces on a plane which is parallel to the axis under the action of the crankshaft connecting rod mechanism (7), and can cross the clapboard (3) to apply work circularly and realize the one-way continuous circular motion mode. The rotary piston cylinder has the characteristics of high energy conversion efficiency, high bearing capacity, widely permitted working media, continuous and stable output, cascade connection capacity, load-carrying self-start, stepless speed change, high-speed response, fast reversing, overload protection, excellent clutch brake performance, and the like.

Problems solved by technology

[0003] Crankshaft-connecting-rod-piston mechanism, its structural feature is that the energy conversion is realized by the positive (reverse) conversion of linear reciprocating motion and rotary motion, the main disadvantages are non-uniform speed, non-equal torque, discontinuous power output, inertial impact, dead As a result, related machines need multi-level wrong-phase linkage, large vibration, high noise, low efficiency, low frequency of work, complex structure, and high processing difficulty

[0004] The turbine mechanism is characterized by the conversion process of fluid kinetic energy in the middle of the positive (reverse) conversion process of fluid pressure energy and mechanical energy. Its main disadvantages are large conversion loss, low efficiency, large volume, high material requirements, and difficult processing. High, low life

[0005] The vane motor mechanism is characterized by eccentric rotation. The main disadvantages are non-constant speed, non-constant torque, non-continuous power output, difficult sealing, low output power, low efficiency, high noise, and easy vibration.

[0006] In other non-mainstream rotary motion mechanisms, there are basically local defects in the above mechanisms. The most important point is that the energy conversion efficiency is low, and the non-continuous stable output
